Penile necrosis resulting from post-circumcision microwave diathermy: A report of 9 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent traditional circumcision for redundant prepuce or phimosis in other hospitals, followed by microwave diathermy for 30 - 60 minutes daily, which resulted in penile necrosis. With no response to conservative therapy, the patients were referred to our hospital at 3 -30 days postoperatively. Of the 9 patients, 5 presented with dry gangrene and 4 with moist gangrene. Six of the patients underwent partial penectomy, including 1 that received penis lengthening.3 months later, while the other 3 underwent total penectomy for total penile necrosis followed by penile reconstruction 3 months later, with deep inferior epigastric perforator (DIEP) flaps and by implantation of the 12th costal cartilage in 2 cases and with epigastric groin island flaps and by urethroplasty in the other.</p><p><b>RESULTS</b>The patients were followed up for 2 - 8 years, and all could urinate smoothly in the standing position. Of the 6 men treated by partial penectomy, 1 received penis lengthening and achieved a penile length of 7 cm and 5 had the remaining penile length of 3 -5 cm, 4 with erectile function and the other 2 capable of sexual intercourse. The 3 men treated by total penectomy achieved nearly normal external appearance of the penis, with a finalized length of (11.7 ± 1.3) cm, a circumference of (11.4 ± 2.1) cm, and a normal feel of the skin. Of the 3 cases of penile reconstruction, 2 achieved sufficient erectile hardness of the penis (grade 3) for sexual intercourse, while the other 1 remained impotent.</p><p><b>CONCLUSION</b>Post-circumcision microwave diathermy may result in penile necrosis, for the management of which, early debridement is necessitated and penile lengthening or reconstruction can be performed according to the severity of the lesion and needs of the patient.</p>

Hand-assisted-drawing-needle running suture with a curved needle: an effective technique to create a W-ileal neobladder / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>An important milestone in the area of urinary diversion was the advent of a series of orthotopic bladder substitution (OBS). However, reconstruction of OBS by the traditional hand suture method (THSM) is a time-consuming process. Stapling techniques are considered to be inferior to hand-sewn methods. We report our experience and functional results in patients with W-ileal neobladder by a hand-assisted-drawing-needle running suture (HADNRS).</p><p><b>METHODS</b>Between April 1993 and December 2011, 347 patients (338 men and 9 women) aged 28 - 77 years (median age: 59 years) underwent radical cystectomy, followed by the creation of a modified W-ileal neobladder by HADNRS with a curved needle. A total of 347 (20 patients in 2003) were evaluated by urodynamic tests.</p><p><b>RESULTS</b>The operative time ranged from 110 to 310 minutes (mean 148 minutes), and the mean time of reconstruction by HADNRS, excluding ureterointestinal and ileouretral anastomosis, was (20.2 ± 4.3) minutes. Histopathological analysis of removed specimens showed that 317 patients had transitional cell bladder carcinoma. Of these 317 patients, 19 also had squamous carcinoma and 13 had adenocarcinoma. Glandularis and prostate cancer occurred in 16 and 14 patients, respectively. Three patients (0.8%) had neobladder abdominal fistula. No other early complications or injury to the surgeon's hands occurred due to HADNRS. Of the 20 cases with urodynamic examinations in 2003, two suffered from daytime incontinence and six had nocturnal incontinence. The maximum capacity of the neobladder was (492.9 ± 177.8) ml, and the maximum pressure within the reservoir at the end of filling was (32.1 ± 8.6) cmH2O.</p><p><b>CONCLUSION</b>Reconstruction of W-ileal neobladder by HADNRS is effective and economical.</p>

Replacement of plaque by buccal mucosa in the treatment of Peyronieś disease: a report of 27 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the clinical results of the replacement of plaque by buccal mucosa in the treatment of Peyronie's disease.</p><p><b>METHODS</b>We performed surgical replacement of the plaque by free autograft of buccal mucosa on 27 patients with Peyronie's disease, ranging in age from 24 to 72 years (mean 53), varying in disease course between 1 and 13 years, with a penile curvature angle of 30 degrees - 80 degrees in erection. Of the total number, 15 patients had the plaque located in the dorsal root, 6 in the dorsal shaft, 3 in the subcoronal shaft and 3 in the ventral shaft of the penis; 24 had 1 plaque, 2 had 2 and 1 had 3, ranging in size from 0.7 cm x 0.7 cm to 1.6 cm x 1.0 cm.</p><p><b>RESULTS</b>Satisfactory results were achieved in all the cases, with no such complications as hematoma, infection, oral numbness, and tightness of the mouth. Of the 24 cases that were followed up for 0.5 to 7 years, complete straightening of the penis was achieved in 21, slight residual curvature (< 15 degrees) was noted in 3, a little shortening of the penis (< 1 cm) in 2, and erectile pain in 3.</p><p><b>CONCLUSION</b>Buccal mucosa, with a stable elasticity and no shrinkage, can be recommended for wide use in the surgical treatment of Peyronie's disease.</p>

Sexual-nerve-Sparing radical cystectomy: experience with 32 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the effect of sexual-nerve-sparing radical cystectomy.</p><p><b>METHODS</b>Thirty-two male patients were treated with sexual-nerve-sparing radical cystectomy in our hospital in the past 5 years. The age of the patients ranged from 38 to 72 years, with the course of the disease ranging from 2 days to 20 years. All of them were potent preoperatively. Radical cystectomy was performed antegradely and retrogradely with the neurovascular bundle spared.</p><p><b>RESULTS</b>The patients were followed up for 6 to 54 months, 3 achieved sexual activity of Grade I, 6 Grade II and 23 Grade III after the operation. The recovery time of erectile function ranged from 2 to 14 months, averaging at 4. 5 months.</p><p><b>CONCLUSION</b>Whenever condition suits, sexual-nerve-sparing radical cystectomy is to be strongly recommended.</p>

Inverted urothelial papilloma: report of 151 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical features, pathology, diagnosis and treatment of inverted urothelial papilloma.</p><p><b>METHODS</b>A total of 151 cases of urothelial inverted papilloma were analysed retrospectively. Of the cases, 134 were male and 17 were female, with a mean age of 54 years old. Most patients complained of painless gross hematuria. The diagnosis could be established mainly by ultrasonic, intravenous urography, retrograde pyelography, cystoscope and pathology. Among them, 7 cases who had the papilloma at upper urinary tract underwent nephroureterectomy except one. One hundred and forty-four cases had the papilloma at low urinary tract, with 124 treated by transurethral bladder tumor resection (TURBT), among which 11 cases accompanying benign prostatic hyperplasia were treated by transurethral prostatic resection, 3 by transurethral resection of prostatic urethral tumor, 15 by partial cystectomy, 2 by total cystectomy.</p><p><b>RESULTS</b>One hundred and eighteen cases were followed up 1 year to 12.5 years (mean 6.3 years). Intravesical recurrence was found in 5 cases. Of them 2 cases developed malignance in 8 and 30 months postoperatively, and 1 case underwent total cystectomy.</p><p><b>CONCLUSIONS</b>Inverted urothelial papilloma is a benign tumor, which appears male predominant. Most of the lesions are found in the bladder. TURBT is the preferred treatment choice for inverted papilloma of the bladder. Although this disease has a good prognosis, regular follow-up observations are necessary.</p>
