Excellent results of Hypospadias repair surgery – TIP urethroplasty (Snodgrass Repair) for distal penile hypospadias

Hypospadias is one of the most common malformations in boys and affects more than 1 lakh kids in India. At Hypospadias foundation and MITR Hospital, Kharghar, Navi Mumbai, India – we see and manage more than 200 kids every year who have hypospadias and need surgery. These cases are either primary (75%) or those have failed surgery elsewhere (25%)- some of them have failed multiple surgeries elsewhere.

We strongly believe that hypospadias surgical correction should not be taken lightly or casually by any surgeons as first hypospadias surgery is the best chance which the child has. Once the first hypospadias surgery has a complication, more surgeries are needed and still the result may not be optimal. Hence, the surgeon needs to be well trained for hypospadias repair procedure and should have a very keen and passionate interest before he takes up any child up for surgery for hypospadias.

Amongst the various techniques for hypospadias surgery, one of the most popular one is Tubularised Incised Plate (TIP) urethroplasty. TIP repair was first described by Prof Warren Snodgrass and it currently constitutes 70% of all distal and midpenile hypospadias repairs across the world. Due to its universal adoption and remarkable results, it is also known as Snodgrass repair. I had the good fortune of assisting Dr Warren Snodgrass during his multiple visits to India when I was a resident in pediatric surgery at All India Institute of Medical Sciences. I keep bumping him into now and then at pediatric urology conferences, the last one of which was European Society of Pediatric urology Congress in Genoa Italy. We received the best paper award at the conference and it was nice to see Dr Warren Snodgrass applauding us.

While TIP repair or Snodgrass urethroplasty has excellent results, case selection before surgery is very important. The criteria are:

  1. Distal or midpenile hypospadias
  2. Mild to moderate chordee which is correctable
  3. Wide pink elastic urethral plate.

In certain selected proximal hypospadias, Snodgrass repair can be used but on a personal level- a long Snodgrass repair may not be the best option in most cases. We have started using Onlay Island flap repair in most of our proximal hypospadias and all distal/ mid penile hypospadias which are unsuitable for TIP Urethroplasty.

Steps of surgery:

  1. Degloving the penis and chordee correction – straightening of the curvature of the penis
  2. Midline urethral plate incision
  3. Neo-urethra formation on a catheter
  4. Second layer coverage with either a dartos flap or spongiosum
  5. Penile skin cover with Byars flap which helps in creating a midline closure on underside of penis. After the healing is finished, penis looks like just a circumcised penis. In some selected cases Prepucial reconstruction can be offered.

In my experience as an expert hypospadias surgeon, while doing TIP urethroplasty everything has to be done meticulously to prevent complications. If I have to narrow down on two things which have really lessened the complications of hypospadias repair with Snodgrass urethroplasty at our centre are:

  • Fashioning a wide caliber neo-meatus- so that there is no narrowing later on
  • Providing a second layer cover on new urethra with either spongiosum or a dartos flap.

Master Soham’s parents stay in Latur, Maharashtra and their son was diagnosed to have a distal penile hypospadias at birth. Worried about multiple surgeries and poor outcomes for hypospadias repair- They searched for the best hypospadias surgeon on the internet and landed up in our pediatric urology clinic at MITR Hospital in Kharghar, Navi Mumbai. We did the surgery using a Snodgrass repair technique in First week of May 2014. The surgery went well and child was discharged the evening of surgery. The dressing and catheter were removed 5 days after surgery and now one month after followup the child has an excellent outcome after hypospadias repair surgery. The cosmetic appearance is excellent with a meatus at the tip of penis, straight penis and just a circumcised appearance.

Parents are also happy and overjoyed.

    Twin babies with Hypospadias- Dilemmas in management!

    Last Monday was like any other Monday. My pediatric urology clinic was full with appointments and I was getting into the rhythm of seeing children with complicated urinary problems and hypospadias. A young couple walked in with twin male babies, each about 7 months old. The boys were naughty and attentive and soon were soaking in the yellow and pink and greens of my outpatient clinic. I looked at the file and asked them the pediatric urological issues for which they were seeing me that day. They said their kid had hypospadias and both of them had hypospadias infact and they wanted to see a Pediatric urologist. Now that was a shocker!! Though this was not the first time that I was seeing twin boys with Hypospadias, but it was that once in two years phenomenon. And more striking since these boys had exactly the same type of hypospadias- which was distal penile hypospadias with mild chordee. Last year I had treated two brothers with hypospadias but the age was 3 and 5 years and thus difference in age was 2 years. The elder one has a mid penile hypospadias while the younger one had a distal penile hypospadias. I suddenly remembered the dilemmas which face a Pediatric Urologist & a Hypospadiologist while treating siblings with hypospadias.

    • Which boy do you treat first – plan according to age – elder first or severity wise and severe hypospadias first and minor later?

    • Whether you do them the same day or one after the other or with some gap of days in between?

    • How will the parents manage two babies getting operated for the same thing at the same time?

    • And if you operate one baby with hypospadias first and second one a few days later- what is the effect on their minds? How do they cope up with a situation where one has undergone a hypospadias surgery and the other one is waiting. Does the second kid get scared seeing the first one in pain after surgery and undergoing hospital visits and checkups? It was a tough situation to be in – for me as a hypospadias surgeon and even more for the parents who will have to care for the children 24×7 after surgery.

    After a lot of deliberation, we decided that we do the hypospadias repair one after the other but on the consecutive days at MITR Hospital & Hypospadias Foundation. We admitted the elder sibling (with more severe hypospadias) for surgery on Tuesday morning and surgery was conducted as the first case in the morning. The younger kid was admitted on Wednesday morning and underwent uneventful repair on Wednesday itself. We arranged for two beds in one room so that both of them can share their side of the story. At least here there was no scope of having a feeling of being left out. Both of them for a fact got a HYPOSPADIAS SURGERY. Recovery period after surgery was smooth and both of them were discharged on Wednesday evening. The kids came back for follow-up on the same day after a week and their catheters were removed the same day. The children pee’d and actually compared their streams and for me luckily- both had good thick straight urine streams without any complications. Deep inside, throughout the recovery period, I was a bit worried about a complication happening. Luckily, everything went well and I had two happy kids with me. Now coming back to present case at hand- where I have a set of twin babies with hypospadias. So going by my previous experience, I think we will stick to the same plan. The only advantage here is that the kids are still less than one year of age and they won’t think much about surgery. I am planning to do them on a Tuesday and a Wednesday and then send them home on Wednesday itself.

    Medicine lends itself to unusual off the script events every day and as we say every patient has a story. For us at Hypospadias Foundation – we believe every child hypospadias has a story with happy ending.

      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.
