Table 2 Pathological anatomies of the urethral stricture and surgical manipulations
Cases | Pathological anatomy of urethral stricture | Surgical manipulations |
|---|---|---|
1 | Coronal meatal stenosis Proximal tiny fistula | Heineke–Mikulicz+Mathieu+Glanular reconstruction Simple fistula repair |
2 | Fossa-proximal meatal stenosis Proximal fistula | Heineke–Mikulicz Flap advancement |
3 | Segmental stricture of penilel shaft urethra with elastic adjacent corpus spongiosum | Heineke–Mikulicz+Corpus spongiosum approximating anastomosis |
4 | Segmental stricture with inelastic adjacent corpus spongiosum of penilel shaft Sub-coronal retreated meatus Tiny fistula | Heineke–Mikulicz+Catheter supporting TIP+Glanular reconstruction Simple repair |
5 | Severely stenotic coronal meatus with epidermis-injured glanular plate Huge diverticulum with good elasticity Pinhole fistula Small glans Peno-scrotal transposition | Stage I: Meatal stenosis elimination; Resuming and widening glanular plate; Diverticulum elimination; Snodgrass; Simple fistula repair Stage II: Mathieu+Glanular reconstruction+Scrotoplasty |
6 | Slightly stenotic meatus Shabby pouch-like Diverticulum without elasticity Fistula Small glans Chordee recurence Peno-scrotal transposition Fistula recurrence | Stage I: Diverticulum elimination; Mathieu+Glanular reconstruction Stage II: Duckett+Scrotoplasty Serial fistula repairs: Turn-over rectangle flip-flap; Y-shaped incision flap advancement |
7 | Complete aplasia of the whole anterior urethra originally Urethral opening stricture Urethral stricture Proximal fistula Proximal urethral dilation Chordee recurrence Coronal meatus | Stage I: Catheter indwelling of the strictured urethra+Proximal urethral-ostomy Stage II: Rectangle flip-flap for ostomy covering Subsequent repairs: Tunica albuginea plication+TIP+Glanular reconstruction |
