Comparison of tension-free vaginal taping versus modified Burch colposuspension on urethral obstruction: a randomized controlled trial.

AIMS: To determine whether the tension-free vaginal tape (TVT) procedure affects the mechanics of voiding in women with genuine stress incontinence (GSI). METHODS: Between July of 1997 and July of 1999, 116 women with GSI in the absence of pelvic prolapse underwent a randomized controlled study of TVT vs. modified Burch colposuspension. The trial was conducted by using a standardized protocol, including strict criteria for excluding preexisting bladder outlet obstruction (BOO). Urodynamic studies including free flowmetry, filling (provocative) and voiding cystometry, and 1-hour pad test were performed before and at least 1 year after the operation. The Blaivas and Groutz nomogram was used as another criteria to assess the pre- and postoperative BOO. RESULTS: Eighteen women were excluded from the study as a result of having preexisting BOO and an additional 8 were lost to follow-up. The comparison between pre- and postoperative variables for each procedure revealed that maximal flow rate of noninvasive uroflowmetry was significantly lower after operation in both groups (P = 0.009, P = 0.010, respectively). Detrusor pressure at maximal flow and urethral resistance were significantly higher and micturition volumes significantly lower after operation in the Burch group (P < 0.001, P < 0.001, P = 0.029, respectively). The difference between pre- and postoperative distribution of the obstruction nomogram of the Burch group was significantly different (P = 0.023). CONCLUSIONS: Based on strict exclusion criteria for preoperative BOO, our findings strongly suggest that with a median 22 months (range, 12 to 36 months) of follow-up, a properly performed tension-free vaginal tape procedure does not cause urethral obstruction.

[Obstructive urethral angioleiomyoma].

OBJECTIVES: To report one case of urethral angioleiomyoma because of the rare site, and to review its main characteristics. METHODS: We report one case of male urethra angioleiomyoma presenting with obstructive symptoms. RESULTS: We performed excision and end to end anastomosis of a small bulbar urethra stenosis. Pathology reported angioleiomyoma. CONCLUSIONS: Angioleiomyoma is a benign tumor arising from smooth muscle within blood vessel walls. It is extremely rare in the urethra. It is more common in females. Recurrence and metastasis are exceptional. It shows scarce or moderate cellularity with predominance of fusiform cells. They may express smooth muscle vimentin, desmin, and actin. The best therapeutic option is resection.

Incomplete urethral obstruction associated with dilatation of the urethra, cystitis, and pyelonephritis in a Vietnamese pot-bellied pig.

A 2-year-old castrated male vietnamese pot-bellied pig examined because of stranguria was found to have severe dilatation and inflammation of the pelvic portion of the urethra accompanied by cystitis and pyelonephritis. The pig had apparently had chronic inflammation of the urinary tract that eventually progressed to incomplete obstruction of the urethra. However, the initial cause of the urinary tract inflammation could not be determined. Possible causes included chronic bacterial infection, traumatic injury during urethral catheterization, and injury to the urethral mucosa secondary to extreme acidification of the urine.
