Adult with Scrotal Hypospadias and multiple failed surgeries – Successful management with Oral Mucosal Graft Urethroplasty

48-year male presented to us with complaints of passing urine from scrotal region since childhood.  He had undergone three hypospadias surgeries elsewhere in the past but still he had multiple urethral fistulas on the underside of the penis. 8 years ago, he developed acute retention of urine, likely due to a suspected urethral stricture. A suprapubic catheter (SPC) was inserted and since then he was on SPC for urine drainage. He visited multiple centres across India from Delhi to Bangalore to Chennai in hope of cure, but everyone dissuaded him for further surgery. Finally, he visited hypospadias foundation for an opinion.

On examination in the OPD, he was primarily draining urine from the SPC. We could see three urinary openings – one meatus was at the penoscrotal junction, and he also had a scrotal and a mid-penile fistula. On clamping the SPC, we checked his urine stream – the stream was poor with a uroflowmetry flow rate of 2.5ml/second and there was spraying of urine.

A retrograde urethrogram was done which showed narrow distal urethra with diverticulum in the rest of distal urethra upto the membranous part of urethra.

We planned a cystoscopy assessment of the proximal urethra following which he was planned for a staged oral mucosa graft urethroplasty.

Stage 1 Oral Mucosa graft urethroplasty:

Cystoscopy showed urethral diverticulum from the penoscrotal region to the membranous urethra. The distal urethra was found to be strictured – we were not able to pass the cystoscope.

Surgery was started by taking a stay stitch over the glans using 4-0 prolene. Complete degloving was done and chordee was checked- no residual chordee was observed. Urethral diverticulum was laid open till normal urethral mucosa was identified. Unhealthy distal fibrotic strictured urethra was removed completely. Proximal diverticulum site was trimmed and proximal urethroplasty done upto the penoscrotal region with 5-0 PDS over a 14Fr silicone catheter. Distal urethral bed was prepared for placement of oral mucosa graft. Glans wings was widely raised.

Oral mucosa graft was harvested from inside of both the cheeks measuring a total of 11cm X 2cm (6cm and 5cm). Graft was defatted slightly and quilted in place using 5-0 vicryl. Pressure dressing was applied, and the catheter was fixed to glans stitch. Dressing and catheter were removed after 10 days.

Graft uptake was 100% with no graft loss. After 21 days, local steroid massages were started and continued till 5 months.

Stage 2 Oral Mucosa graft Urethroplasty:

Graft was soft and supple at 6 months after graft placement. Surrounding skin was also healthy. At stage 2, graft edges were marked. Local anaesthesia (lignocaine with adrenaline) was infiltrated at the marked site. U shaped incision was given and deepened till the corpora. Urethroplasty was done over a 14Fr silicone catheter with 5-0 Vicryl in 2 layers. Local dartos flaps were used for second layer coverage. Skin was closed in 2 layers and dressing was done. Suprapubic cystostomy was done using 14 Fr malecot’s catheter. Dressing inspection was done on post operative day 4 and every 4th day thereafter. During every dressing change betadine wash was given and re dressing was done. Per urethral catheter was removed on post operative day 14 and suprapubic catheter was removed on post operative day 21. Patient was passing urine in good stream without pain or leak after catheter removal. At his final checkup, 6 months after surgery- the cosmetic result was good, and the patient was passing urine from the glanular meatus in good stream.

Never give up hope even if multiple hypospadias surgeries have failed

Hypospadias treatment in adults especially if previous surgeries have been unsuccessful, is a difficult task. The complexity of the condition and the potential for complications can often necessitate a staged repair, maybe even in 3 stages. A lot of adults in this century, underwent surgery as children way back in the past and some of them did not get good results even after multiple hypospadias surgeries. With advancing knowledge and expertise, the results of hypospadias repair (urethroplasty) in such cases have improved.

Reasons for multiple surgeries in adults with hypospadias may include:

  1. Development of complications: The common complications which can occur after hypospadias repair are urethral strictures, fistulas, diverticulum, hairy urethra or residual chordee. These may require additional surgical intervention.
  2. Unsatisfactory cosmetic results: The patient may be unhappy with the appearance of their penis following the initial surgery.

An adult with multiple failed hypospadias surgeries, generally has no normal hairless penile skin left for hypospadias repair. Hence in such patients, it may be better to use skin from inside the mouth for making the new passage. The skin is taken from inside of cheek or lips and is called oral mucosa. The defect heals very fast and generally without complications. The oral mucosa graft adapts to penile location very well and has great long-term results in redo hypospadias repairs. While some of these cases are suitable for a single stage surgery, some may require two stage surgery depending on the severity of the defect. Nonetheless, Oral Mucosa Graft Urethroplasty remains a great option with best long-term results for children and adults with Failed Hypospadias.

It’s important to note that multiple surgeries can be physically and emotionally demanding. It’s essential to have a strong support system in place and to communicate openly with your hypospadias surgeon about your concerns, experiences and your expectations. If you have undergone multiple hypospadias surgeries, it’s crucial to consult a qualified hypospadias surgeon who can assess your condition and recommend the best treatment plan.

Hyperbaric Oxygen therapy

Hypospadias repair surgery is a very delicate and demanding surgery.  We have realized that hypospadias repair procedure is not a surgery which can be done casually or as one of the many surgeries which a surgeon does. Best results of hypospadias surgeries are seen only when the surgeon dedicates his time and energy in pursuing the art and science of hypospadiology. Results keep on improving day by day and year by year. With more than 5000 hypospadias repairs done over last 16 years, Hypospadias Foundation at MITR Hospital, Navi Mumbai, India provides the best results in hypospadias surgeries. Children have travelled from all over India and other countries such as Nigeria, Greece, Bangladesh, Iraq, UAE to get treated under Dr Singal’s care for hypospadias.

To get the best outcome in hypospadias, it requires a big team effort which includes hypospadias surgeons, assistants, well trained OT staff and post-surgery caring staff.

Along with post operative care which includes post operative dressing, wound care, medicines etc we have also found that hyperbaric oxygen therapy is beneficial in hypospadias. Here is a guide regarding hyperbaric oxygen therapy in hypospadias.

1.What is hyperbaric oxygen therapy?

Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. The increased pressure allows more oxygen to dissolve in the blood which is then delivered to the tissues. When tissues are injured or under stress, they need adequate supply of oxygen to function. This HBOT ensures extra oxygen supply to the tissues and this temporary increase is maintained even after the sessions are done.

2.How does hyperbaric therapy help in hypospadias healing?

In HBOT, the air pressure is increased 2-3 times higher than the normal air pressure. This causes the lungs to gather more oxygen. This extra oxygen stimulates the growth factor and stem cells to promote healing and fights bacteria after hypospadias surgery.

3.What type of hypospadias repairs requires post-surgery hyperbaric oxygen?

In hypospadias repair, HBOT is required in following cases:

a.Redo hypospadias (hypospadias after previous multiple failed attempts)- after multiple previous surgeries, the vascularity of the penile tissues may be poor. We can expect slow healing in these cases during future repairs. HBOT in these cases will ensure good oxygen supply and will promote growth factors to aid in formation of new tissues to promote healing.

bAdult hypospadias: The cell turnover rate in adults is slower than children. Post surgery there is high risk of infection in adults in turn leading to pus formation and wound dehiscence. HBOT ensures increased oxygen delivery to these tissues which in turn will help in tissue regeneration, infection prevention and better healing in the post operative period.

4.What is the typical schedule and cost of hyperbaric oxygen therapy?

Typical schedule for HBOT is 7 sessions in the post operative period starting from 24-48 hours after surgery. These 7 sessiares will cause temporary rise in oxygen levels which is maintained even after the sessions are complete. It’s a 1-hour session per day. The chamber is compressed to 2.0 atmospheric pressure. 2-3 air breaks are given in each session (oxygen level is decreased from 100% to 21% for 5 mins in the 1 hour period). If a child is undergoing HBOT then a parent along with the child will be allowed to sit in the pressurized chamber. Continuous monitoring is done during the session. The average cost of HBOT session in Kharghar, Navi mumbai is 3500 INR or around 40 USD per session.

At hypospadias foundation, more than 50% of the cases are the ones with previous failed surgeries. Every year we perform more than 250 hypospadias surgeries and more than 20% of these are adults suffering from hypospadias. All these patients come to us with a lot of hope and trust us that we will treat their hypospadias. Our main aim of starting HBOT was achieve good results and decrease the risk of hypospadias complications. With HBOT we have been able to achieve it and strive to do better in the future. Over the last few years, Dr A.K.Singal, rated as the best hypospadias surgeon in India, has an expertise and a special interest in managing failed hypospadias cases. He along with Dr Shenoy have standardized the hypospadias management protocol so efficiently that success rates have increased significantly.

Dr Singal presented the following lectures and papers in the World Congress:

  • Buccal inlay graft for failed hypospadias- Dr Singal showed technique of buccal (oral) mucosa graft inlay surgery and its results in failed hypospadias cases.
  • Considerations in adult hypospadias repairs- Adult hypospadias are difficult to manage especially if the surgery done in childhood has failed. Dr Singal showed innovative surgery techniques for such adult hypospadias cases for best outcomes.
  • Reimagined Byar’s flaps for staged hypospadias repairs- For hypospadias with severe chordee, it is important that the penile curvature gets fully corrected in first stage and then second stage surgery is done for bringing the urethra to the tip of penis. In expert hands the results of two stage surgery for hypospadias with severe chordee is very good. Dr Singal showed finer nuances of surgery to achieve best results to the audience.
  • Parental Awareness survey for families with hypospadias: Families of children or adults with hypospadias are often not fully aware of the extent of disease and what it means in the long run. Dr Singal and his team conducted a study of 150 families to understand about their concerns about hypospadias and their knowledge level about the disease/ surgery.

Overall the three-day conference resulted in great mutual exchange of ideas and also helped younger generation of surgeons learn from eminent faculty from all over the world.

Don’t give up hope on Failed Hypospadias

This is an interesting and inspiring story and I thought I will share it with everyone who has an interest in the field of hypospadias.

About 6 months back, a 14 years old boy was brought all the way from Nasik to my Pediatric Urology clinic at MITR Hospital in kharghar, Navi Mumbai. The parents did not seem to very well educated and were from a farming background. The father was in some class 4 government job. I was wondering why they would travel for 8 hours to a small place like kharghar to see me. Also the age seemed to me a little bit older than the usual age which I see in my clinic. I was intrigued.

The boy seemed little uncomfortable and had furtive glances here and there. Parents and relatives were fidgety too. The consultation began – I asked what brought them to Kharghar. They said that their kid has hypospadias and has undergone 5 surgeries till now but still passes urine from below. I asked them “how did they find me”. They said maternal uncle of the boy knows internet and found me while looking for information about hypospadias. So there it was Internet the great enabler at play.

I went through the case records dating 10 years back. The kid was born with scrotal hypospadias and underwent first major surgery at 2 years of age to straighten the penis (chordee correction) at a top medical college at Mumbai. Post that there were multiple attempts to make a new passage initially using native penile skin and then lining of urinary bladder twice and finally skin graft. Everything had failed and the last surgery was about 5 years back when it was told that there is no hope of the boy having a normal urethral opening at tip of penis. Now I knew the reason of furtive glances and fidgety mannerisms.

On examination, the boy had the urinary opening right near the anus, the penis was still slightly bent (chordee) and there was lots of scarring on underside of penis with deep pits and ragged skin edges. Further there seemed to be a couple of blind passages and left testis also looked higher in position, may be it was caught up in the scar process. Since the opening was even behind the scrotum, the child had to sit in the toilet and pass urine. Overall, the case seemed like mother of all hypospadias.

I counseled the parents and set out a planned staged correction of hypospadias. I told them it will be tough and they will need to be patient and have faith.  The plan was to bring him back to his original anatomy first and the reconstruct the entire new urinary passage. As the first stage, I planned to remove all the scarred skin and straighten the penis. In the raw area thus created I was planning to put buccal mucosa graft which is nothing but the inner layer of skin inside the mouth more specifically lips and cheeks. This buccal mucosa graft takes about 3-4 months to heal and then we planned to use this patch to create a new urinary passage. This would give a sure result and the buccal mucosa graft being moist and soft would not have any issues being in touch with urine. Also there would be no hair growth inside the passage in the future.

Well, the parents were convinced because probably I was the first hypospadias surgeon to offer them any hope. So we all set out on our task, an uphill journey.

We took up VW for first stage surgery – expecting about 4 hours of surgical time. But we ended up consuming about 7 hours by doing the following

  • Cystoscopy and ascertaining usable urethral passage
  • Excision of all scar tissue on underside of penis
  • Straightening the penis – chordee correction
  • Closing the perineal urethrostomy and establishing a penoscrotal meatus.
  • Correcting the penoscrotal transposition
  • Left orchioexy was needed as the left testis was caught in the fibrosis
  • Buccal mucosa graft

But we were satisfied at the end of it all. We could not think of a shortcut as the child had been through a lot. The child remained in the hospital for 7 days and the graft healed very well. At removal of catheter, he was able to pass urine from the penoscrotal meatus without difficulty and was finally able to stand up and pass urine without wetting his pants. I could see the change in his behavior and he seemed more interactive now with me and the hospital staff. We had moved forward by an inch I guess!

4 months later we admitted him again for second stage urethroplasty. The previous graft had healed very well. We could easily make a new urethra just rolling the previous graft plate. This was done over a 12 French silicone catheter without any stress. To ensure full healing we also used a tunica vaginalis graft from the right testis to cover up the suture line.

As I write, the child has finished one month follow-up after urethroplasty surgery and is recovering well from the surgery. He is passing urine currently from the tip meaning the repair is holding well. The final result is yet to be seen and may be another minor procedure may be needed but the journey has been great. Our mood is upbeat and we are sure that we will reach the destination this time or another short journey may be needed 3 months from now. The fact of the matter is that we enjoyed the journey.

It is challenges like these when everyone else has given up, we still gear up and try to do our best for these kids. We may not pass in one attempt but eventually we will. Even if 20% need another surgery that is still acceptable as the final goal can still be achieved.
