[Xanthogranulomatous pyelonephritis. Retrospective study].

The incidence of PGX in our setting is low (0.67%). Middle-aged women comprise most of our cases. This disease process is usually unilateral; 53.2% of the present series had right-sided renal involvement. Over the past 17 years, 135 cases of histopathologically-documented XGP have been recorded at our hospital. Sixty-three cases were studied retrospectively. Patient history, symptoms and signs, and data gleaned from physical examination are presented. Similarly, patient outstanding pathogenetic features are described. Preoperative diagnosis of XGP is difficult. The availability of high resolution imaging techniques has enhanced diagnostic accuracy. Urinary cytology permits preoperative diagnosis with an accuracy rate of 80%. The postoperative prognosis is excellent.

[Treatment of bladder instability using intravaginal electric stimulation (intrarectal)].

Fourteen patients (13 females, 1 male) with urinary incontinence from bladder instability were treated with intravaginal (intrarectal) electrical stimulation. Good results were achieved in 57.1% of the cases. The foregoing finding shows that intravaginal (intrarectal) electrical stimulation may constitute a therapeutic option in urinary incontinence from bladder instability.

[Participation of bladder dysfunction in urinary incontinence after prostatectomy].

Twenty-four patients with post-prostatectomy urinary incontinence were submitted to clinical and urodynamic evaluation. The clinical evaluation analyzed urinary symptoms and included rectal examination of the prostate lodge, neurourologic examination (perineal sensitivity, anal tone, bulbocavernous reflex, voluntary control of anal sphincter). The urodynamic study consisted of flowmetry, cystomanometry, detrusor pressure/micturition flow test and videocystography. An unstable bladder was demonstrated in 62.5% of the cases. Bladder dysfunction was recognized in 75% of the cases. Involvement of the striated periurethral sphincter was demonstrated in no patient. The clinical data did not provide orientation. No relation was observed between the urodynamic data, type of surgery, and amount of prostate removed. The urodynamic data appear to have a prognostic significance.

[Dysfunction of the contractile capacity of the detrusor muscle in post-prostatectomy urinary retention].

We report on 23 consecutive patients with urinary retention following prostatectomy for benign prostatic hypertrophy. The patients were clinically and urodynamically evaluated. Urodynamic work-up included flowmetry, cystomanometry, detrusor pressure-micturition flow test, and videocystography. The involvement of detrusor contractility in urinary retention was observed in 60.87% of the cases and was ascribable to lower urinary tract obstruction in 39.19%. These data permitted instituting correct treatment.
