Objective To summarize the cl inical effect of a new operative technique of combining penis flap with buccal mucosa graft in the treatment of phall ical urethral stricture. Methods From March 2006 to December 2007, 6 patients with phall ical urethral stricture, aged 3-26 years old, were treated by the method of combining degloved penis flap with buccalmucosa graft. All of them had the symptom of dysuria within 2-10 months after urethroplasty. The urethral stent of highelasticity sil ica was kept for 2-3 weeks after operation. Results Five patients’ incisions obtained heal ing by first intention with satisfying urination and there were no compl ications. Sl ight infection appeared in 1 case at 3 days after operation, with small quantities of suppurative exudate in the incision, which healed through open drainage and washing with antibacterial 2 weeks later. The thinning of the urinary stream was presented at 1 month after operation, and then disappeared after 2-month urethral dilatation. All the 6 patients were followed up for 6-10 months and they felt satisfied with emiction. They had a l ittle bit thicker urinary streams than those of their own age. There was not any residual urine in bladder after emiction. Conclusion The method of combining penis flap with buccal mucosa graft is effective in the treatment of phall ical urethral stricture. It deserves to be popularized due to its simple operation and credible effects.
Objective To investigate the effect of ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias. Methods From August 2000 to December 2005, 20 patients with anastomotic stricture after hypospadias repair were treated with ventral urethroplasty. The age ranged from 2 to 27 years with an average of 6.4 years. All patients showed dysuria after operation. Main clinical manifestation included dysuria and acraturesis. Interruption of urinary stream occurred in 17 cases; of them, 3 cases had urinary stasis and 4cases had frequent micturition, urgent micturition and pain in urination. Urethrography and cystourethrography showed 0.5-1.0 cm stricture with proximal dilat ion of urethra in 16 cases and obvious diverticularization in 9 cases. Urine routine examination showed that white blood cell was ++ to ++++ in 16 cases and pus cell was ± to++ in 13 cases.Results Twenty cases were followed up 2 months to 4 years (mean 2.3 years). All the cases achieved good results in urination with normosthenuria and normal force of urinary stream. No recurrent stricture, urethrocutaneous fistula, or penile curvature occurred. The cosmesis was satisfactory, and the results of urine routine examination was normal. Conclusion Ventral urethroplasty for postoperative anastomotic stricture inpatients with hypospadias is a simple and effective procedure.
Objective To search for a new method to repair distal urethral stricture resulting from urethroplasty of hypospadias. Methods FromFebruary 2000 toMarch 2004, 16 patients with distal urethral stricture were treated by use of cutting stricture urethra and their distal urethra were reconstructed with phallic flap. Results All operations were successful without complication of flap necrosis. After 7 days of operation, the patients had free micturition and thick stream of urine. Eleven patients were followed 2 months to 4 years, the satisfactory result was obtained. Conclusion It is a simple and good method to reconstruct the distal urethra by superimposing the phallic flap on the cut stricture urethra after urethroplasty of hypospadias.
ObjectiveTo discuss the reoperation methods of urethral stricture after urethroplasty of hypospadias and their effectiveness.MethodsBetween September 2010 and April 2018, 169 patients with urethral stricture after urethroplasty of hypospadias, who underwent ineffective conservative treatments first, were accepted. The age ranged from 1 year and 7 months to 41years with a median age of 5 years and 8 months. The stricture located at the external urethral orifice in 80 cases, internal anastomosis connection in 87 cases, and constructed urethra in 2 cases. The symptoms of urethral stricture occurred at 2 weeks to 52 months after urethroplasty, with a median time of 4.5 months. The patients with external urethral orifice stenosis were treated with urethral meatus augmentation (74 cases) and urethral advancement (6 cases). The patients with internal anastomosis connection stenosis were treated with internal urethrotomy with urethroscopy (10 cases), urethrotomy and one-stage urethroplasty (26 cases), and urethrostomy (51 cases) including 43 cases of two-stage urethroplasty. The patients with constructed urethral stricture were treated with urethrolysis.ResultsOne hundred and fifty-four patients were followed up 6–86 months with an average of 47 months. The stenosis was relieved in 137 cases, and re-stenosis in 12 cases, urethral fistula in 4 cases, all of which were treated successfully. In addition, 1 case with mild urethral diverticulum did not need to be treated.ConclusionIf it is ineffective for the conservative treatment of urethral stricture after urethroplasty of hypospadias, appropriate surgical treatments could be selected according to the location and length of the stricture, local tissue conditions, complications, and so on.
Objective To investigate the therapeutic effect of pedicled scrotal septal flap urethroplasty on longsegment posterior urethral stricture and to assess its appl ication value. Methods From January 2003 to December 2007, 24 patients (age range, 6-54 years old) with long-segment urethral stricture underwent pedicled scrotal septal flap urethroplasty.The duration of the disease was 1-5 years. The stricture was caused by traumatic urethral injury or disruption in 22 cases,postoperative compl ication of suprapubic transvesical prostatectomy in 1 case, and recurrent urethral infection due to long-term indwell ing urinary catheter in 1 case. Urethroscopy or cystourethrography examination confirmed that all cases had urethral stricture 2.0-5.5 cm in length. Eleven cases were compl icated with urethral false passage, 6 with urethral fistula, 2 with intestinal fistula, and 6 with erectile dysfunction. The result of excretion urography of bilateral upper urinary tracts was negative in all cases. Pedicled scrotal septal flap 2.5 cm × 2.0 cm-6.5 cm × 2.5 cm in size was harvested during operation, and urethroplasty was performed. Results Volume of blood loss during operation was 100-500 mL (average 270 mL). The operative time was 90-220 minutes (average 135 minutes). All flaps survived. All wounds healed by first intention. All patients had normal urination after operation. Over the follow-up period of 12-36 months (average 18.6 months), 1 of the 24 patients suffered from urinary incontinence, 2 from urethral stricture, 1 from urethral stricture and urethral fistula, and 1 from urethral diverticulum around the distal anastomosis. Those patients got normal urination after symptomatic treatment. No urethral stone, urinary incontinence, and new case of erectile dysfunction occurred. The maximum urinary flow rate 16 months after operation was 14-21 mL/s (average 17.6 mL/s). Voiding cystourethrography 22 months after operation showed unblocked urinary tract and no formation of stricture and fistula. Conclusion Pedicled scrotal septal flap urethroplasty, featured by simple operative method, easy flap harvest, and high survival rate of flap, is one of safe and effective methods for treating long-segment posterior urethral stricture.
Objective To explore and describe the clinical feasibility and value of reconstruction of complex urethral stricture with free postauricular graft. Methods Urethroplasties-with free postauricular grafts were performed in 17 patients with complex urethral strictures, including 6 cases in anterior urethras and11 cases in posterior urethras.The grafts were transplanted onto the opened urethras in the first stage;6 months later, the new urethras were shaped with the second stage urethroplasties in 14 patients.There patients succeeded in single-stage urethroplasties. The urethras and bladders were washed with antibiotic solution everyday after urethroplasties. Results Good- and satisfactoryresults were obtained in 15 cases 6 months after urethroplasties, regardless of the strictured sites and lengths. Maximal urinary flow rates ranged 14-32 ml/s. There were 2 cases accompanied with complications 6 months after urethroplasties,1 case of fistula was repaired,1 case of severe urethral stricture was reconstructed with opposite side free postauricular graft later. Three patients had mild urethral strictures 6 months after urethroplasties, they were cured with urethral dilatationsfor 4-8 times. Conclusion Reconstruction of complex urethralstricture with freepostauricular graft is a good and effective method to treat long or complex urethral strictures, especially for patients without adequate foreskin or penis skin.
