5-year-old boy with distal penile hypospadias, had undergone two surgeries somewhere else and came to Hypospadias Foundationnted with complaints of difficulty in passing urine from the meatus and urine leak from the distal penile region. On clinical examination, there was residual chordee, fistula in the distal penile region and penile torsion to the right.

At our centre, he was planned for cystoscopy, chordee assessment and single or two stage repair based on the cystoscopy findings. On cystoscopy, we found stricture of length 1.5cm in the distal urethra (beyond the site of fistula) and normal proximal urethra.

As a first step, the penis was degloved. Fibrotic bands were released during degloving. Chordee was assessed by artificial erection test and no chordee was noted. The dorsal penile skin (residual prepuce) looked healthy with preserved vascularity. Hence, we planned to go ahead with the urethroplasty in single stage using an onlay flap from this residual prepuce.

15x8mm flap along with the good vascular dartos tissue was raised from the dorsal side. Flap was rotated around the side of the penis and brought to the underside of the penis for urethroplasty. Urethroplasty was done using 6-0 PDS over a 7Fr infant feeding tube. Dartos tissue was fixed on either side to cover the urethroplasty. Glans wings were raised widely and glansplasty done using 6-0 PDS. Excess skin was trimmed on the right lateral side and repositioned to correct the penile torsion and to achieve a better cosmetic result.

Single stage hypospadias repair in a child using onlay flap from residual prepuce after previous failed surgeries

Hypospadias is a birth defect in boys where the urinary opening is on the underside of the penis. One of the popular techniques used for hypospadias repair is a Prepucial Onlay Flap urethroplasty. In this surgery, a well vascularized flap is raised from the dorsal prepuce and used to reconstruct the urethra.

This technique can also be used in failed hypospadias in the presence of residual prepuce and with no or minor chordee. The success rate of onlay flap in a failed hypospadias varies depending on several factors including the severity of the hypospadias, the surgeon’s experience, vascularity of the penile skin etc. During the surgery, flaps must be carefully raised preserving the vascularity otherwise there is risk of flap necrosis and complete dehiscence. Post surgery dressing should not be tight because it can cause compression of the flap and compromise the vascularity. This repair has good outcomes when performed by an experienced hypospadias surgeon.

If your child has undergone prior hypospadias repairs and developed a complication, then do consult an expert hypospadias surgeon for your child. Discuss the best options for your child and take an informed decision from the best in the field of hypospadias.

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 4^th 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.

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.
