Perforation of the ileum as a complication of suprapubic catheterization.

Although suprapubic catheterization is a useful technique in managing the postoperative patient who requires prolonged urinary drainage, the potential exists for iatrogenic damage to the abdominal contents. Two cases of perforation of the distal ileum occurring during catheter placement after vaginal procedures are presented. Such complications may be kept at a minimum by adequate bladder distention, careful bladder palpation, placement of the patient in the Trendelenburg position before filling the bladder, and catheter insertion before closure of the surgical incision.

Significance of urethral vascular pulsations in genuine stress urinary incontinence.

Urodynamic tracings of 100 women with genuine stress incontinence revealed urethra vascular pulsations in 15 patients, while 85 lacked vascular pulsations. The presence of vascular pulsations correlated with the maximal urethral closure pressure and identified a subgroup of genuine stress incontinence with normal sphincter strength and reflex activity. The only identifiable cause of stress incontinence for each patient in this group was a deficiency in the anatomic supports of the urethrovesical junction responsible for poor transmission of intra-abdominal pressure to the urethra during stress. Those patients lacking vascular pulsations demonstrated resting sphincter weakness as well as decompensation of the sphincteric mechanism with changes in bladder volume and posture. In most women with genuine stress incontinence, the etiology is a combination of urethral sphincter dysfunction and poor anatomic support of the urethrovesical junction.

Vesical instability: urodynamic parameters by microtip transducer catheters.

Thirty-two women with vesical instability underwent detailed urodynamic evaluation with microtip transducer catheters. Dynamic urethral profilometry demonstrated combined incontinence (genuine stress incontinence and vesical instability) in 13 patients (41%). Supine cystometry with the subject at rest demonstrated vesical instability in only 21 patients (66%). In 11 patients (34%) either provocative maneuvers or erect cystometry was required to make a diagnosis of vesical instability. Seven patients (22%) had evidence of urethral instability before the onset of involuntary detrusor contractions.
