RESUMEN

OBJECTIVES: To report our 8-year experience with buccal mucosa onlay urethroplasty with the dorsal approach in the treatment of bulbar urethral strictures. The buccal mucosal graft is widely used as an effective option for urethral reconstruction. METHODS: Since June 1994, we have treated 65 patients with bulbar urethral strictures with buccal mucosa urethroplasty. A free graft of buccal mucosa was used as a ventral onlay in 9 patients and as a dorsal onlay in the remaining 56 patients. The bulbar urethra was isolated from the corpora. Endoscopic urethrotomy was performed dorsally. The graft was obtained from the lower lip and sutured to the urethra and corpora cavernosa. A transurethral grooved catheter and suprapubic drainage was maintained for 7 and 14 days, respectively. RESULTS: The median follow-up was 41 months (range 6 to 94). The overall recurrence rate was 3% (2 of 65). One recurrence occurred in a ventral onlay patient and one in a dorsal onlay patient. Minor complications occurred in 9 patients (14%). CONCLUSIONS: Buccal mucosa dorsal onlay urethroplasty is an excellent option for the treatment of bulbar urethral strictures.

RESUMEN

OBJECTIVES: Immunotherapy with Bacillus Calmette Guerin (BCG) has been widely used recently as primary option for treatment of high grade superficial (G3T1) carcinoma of the bladder. We describe our long term experience of therapy of G3T1 bladder cancer. METHODS: From January 1982 to December 2000, 785 patients were diagnosed with superficial bladder cancer. All patients underwent preoperative CT scan and transurethral resection of the bladder. Eighty-six patients (11%) had histological high grade superficial bladder cancer infiltrating the lamina propria. This group was treated with the following schedule of BCG Pasteur strain plus maintenance. Four cycles BCG, 6 instillations per cycle, first cycle weekly x 6, second cycle every 2 weeks x 6, third cycle monthly x 6, fourth cycle (maintenance) every 3 months x 6 instillations. RESULTS: The median follow-up is 91 months (30-197 months). The overall recurrence rate was 35% (30/86). The median time to recurrence was 29 months (5-128 months). Of these patients, 12 (14%) had progression at a median follow-up of 16 months (range 8-58 months). Cystectomy was needed in 8 (9%) patients. Death due to disease occurred in 5/86 (6%) patients. One patient died due to adenocarcinoma at the ureterosigmoidostomy site. Sixty-four (74%) patients are alive at a median follow-up of 71 months (range 28-197 months). Sixty patients (70%) are alive with an intact bladder. CONCLUSIONS: Treatment with BCG is a feasible conservative therapy for patients with primary G3T1 transitional bladder cancer. Long term results of BCG treatment are excellent. Cystectomy shouldn't be considered first line treatment for high grade superficial carcinoma of the bladder.

RESUMEN

PURPOSE: Prostate cancer detection on standard sextant biopsy is considered inadequate. Various biopsy protocols have been introduced to improve cancer diagnosis. We report our experience with transperineal 12-core prostate biopsy. MATERIALS AND METHODS: In a prospective study 650 patients underwent prostate specific antigen (PSA) measurement during a 15-month period, of whom 141 with PSA greater than 4 ng./ml. also underwent transperineal 12-core prostate biopsy using the fan technique. Median PSA was 8 ng./ml. (range 4.1 to 5,000). RESULTS: Prostate cancer was detected in 72 of the 141 patients (51%), including 44 of the 97 (45%) with PSA between 4.1 and 10 ng./ml. This incidence is higher than previously reported in the literature using other biopsy techniques. Disease was low grade Gleason 2 to 4 in 4 cases (5%), intermediate grade Gleason 5 to 6 in 26 (35%) and high grade Gleason 7 to 10 in the remaining 42 (60%). CONCLUSIONS: A high cancer detection rate is achieved by 12-core transperineal prostate biopsy. Most tumors represent clinically significant cancer. Further randomized trials are required to confirm these data.

RESUMEN

Demonstration of malignant cells in blood specimens collected during transurethral resection of the prostate (TURP) has implicated TURP in the dissemination of prostatic cancer. Of 153 patients who underwent radiation therapy for prostate cancer between January 1977 and June 1990 and were retrospectively analyzed, 93 were evaluable. Fifty-nine patients required TURP before radiation therapy for prostatic obstruction (BPH and/or cancer); the remaining 34 patients underwent radiation therapy after fine-needle aspiration biopsy. No statistically significant difference in failure rate could be detected between these groups, with a failure rate of 47% (28 of 59 patients) at a median follow-up time of 49 months (range, 8 to 146 months) in the TURP group versus a failure rate of 47% (16 of 34 patients) at a median follow-up time of 50 months (range, 3 to 122 months) in the group who underwent biopsy only (Fisher's exact test, P = 0.23). Within the confines of this retrospective study, it appeared that TURP did not enhance the development of metastatic disease.
