Urorectodynamic evaluation of healthy volunteers.

Twelve female and 8 male healthy volunteers underwent urorectodynamic evaluation. Mean bladder capacity was 594 ml. and mean maximal vesical pressure 12.

Clinical and urodynamic evaluation of urethrocystopexy for stress urinary incontinence: preliminary report.

Thirteen patients presenting with stress urinary incontinence associated with a notion of urgency were evaluated. Each patient underwent a full clinical and paraclinical preoperative evaluation. The urodynamic evaluation included flowmetry, urethral profile, cystometry lying down and standing, and intrarectal pressure measurement.

Urorectodynamics in patients with colonic inertia.

Sixteen female patients with colonic inertia and 12 control women underwent manometric evaluation of their bladder and rectal cavities. After subcutaneous injection of 0.035 mg.

Fibroepithelial tumour of the renal pelvis.

From a statistical viewpoint, almost all renal pelvic tumours may be considered to be transitional cell carcinomas. Only six benign pelvic tumours have been reported in the English literature. The author describes one such case.

Urethral pressure changes in reflex micturition.

The mechanism and pattern of urethral pressure changes during bladder filling and voiding were investigated in anesthetized female dogs. A series of experiments was performed involving simultaneous recording of intraurethral and intravesical pressures before and after surgical separation of the bladder from the urethra. Similar experiments were done after pharmacologic blockade of the striated muscles, alpha-adrenergic receptors, and autonomic ganglia.

Compliance of the bladder: an attempt to establish normal values.

A study of 100 normal cystometries was undertaken to establish compliance values. The results seem to discourage the practical application of this parameter due to the absence of normal distribution and extreme scatter of values.
