ObjectiveWe report additional technical modifications and extended application of proximal TIP hypospadias repair in consecutive patients operated by a single surgeon.MaterialsDuring a 39-month period, 36 patients underwent primary proximal hypospadias surgery, with 26 undergoing TIP and 10 two-stage repair for a thin urethral plate (UP) (1) or ventral penile curvature (VC) requiring UP transection (9). Of the TIP repairs, 16 had UP elevation from the corpora cavernosa to facilitate VC straightening while maintaining the UP for urethroplasty. All TIP patients underwent two-layer urethroplasty with tunica vaginalis coverage over the neourethra.ResultsWith mean follow up of 12 months (2–38) in 24 TIP patients, 16 had calibration and 11 urethroscopy 6–12 months postoperatively. Complications occurred in three (13%), glans dehiscence (2) and neourethral stricture (1), which represents a significant reduction versus our prior reports. Non-randomized preoperative testosterone in 8/24 with follow up did not influence complication rates. TIP incision of the elevated UP did not divide it into separate strips, or impair vascularity.ConclusionsDissection of the UP from the corpora facilitates correction of VC while preserving the plate, without increasing TIP urethroplasty complications. Overall, complication rates for TIP have significantly diminished with technical modifications and experience. The role for neoadjuvant hormonal therapy remains unclear. Despite straightening VC preserving the UP, intraoperative assessment deemed it unsuitable for TIP in one case (4%).
