[Urinary continence after radial prostatectomy. Prognostic factors and recovery time].

OBJECTIVES: To assess the urinary continence after radical prostatectomy and its evolution over time. To analyse possible prognosis factors. MATERIAL AND METHODS: We have reviewed 101 patients that have undergone radical prostatectomy. We define "continent patient" as that one who doesn't require any type of urinary protection. By means of Kaplan-Meier method, we evaluate the recovery of continence along time. We analyze potential conditional factors (age, stage, surgery technique, surgery experience,...). The statistical tools used are: chi-square, Fisher, Cox regression, T-test and Kaplan-Meier. RESULTS: Median monitoring time: 27.33 months. 80% are continent patients, 48.7% of which reach maximum continence before the 3rd, month is due and 17.5% after the 6 months (2.5% between 9-12 months). Their probability of becoming "continents" during the first 4 months es 0.4692. patients under 70 years old recover continence before those who are over 70 years old (medians: 3.51 months and 5.67 months respectively, p = 0.0211). CONCLUSIONS: The recovery of continence takes place progressively and a 17.5% of patients reach plain recovery in the 6-12 months period after surgery. The evaluation of the surgery treatment to correct incontinence should consider the possibility of "spontaneous" recovery in a 2.5% of patients in the 9-12 months period after surgery. Age affects negatively the recovery time; it is significantly less for patients under 70.

[Leiomyoma of the bladder].

OBJECTIVE: To report a case of leiomyoma of the bladder, a benign tumor that accounts for 0.43% of bladder tumors. The literature is briefly reviewed. METHODS/RESULTS: A 64-year-old male with prostatic syndrome is described. The preoperative evaluation showed bladder lithiasis and signs compatible with prostatic hypertrophy, but no evidence of a bladder tumor. Endoscopic evaluation, however, revealed a tumor in the bladder neck. Transurethral resection of the tumor, prostate and endoscopic lithotripsy of the bladder were performed. The anatomopathological findings showed leiomyoma of the bladder. The postoperative course was unremarkable. CONCLUSION: Leiomyoma of the bladder does not present specific symptoms and is frequently an incidental finding. The diagnosis is based on the results of the anatomopathological analysis of the specimen.

[Renal oncocytoma: infrequent presentation form].

Case report describing a solid renal mass as an incidental finding while evaluating a different condition. This is an oncocytoma infiltrating perirenal fat. The various aspects of the process are described.

[Acute kidney failure secondary to inguinoscrotal bladder hernia].

Bladder hernia is not a rare pathological condition, with a frequency between 0.3% and 3%, reaching the 10% between patients older than 50 years. Massive bladder hernia is less frequent and very rarely ureterohydronephrosis is associated with this pathology, given that the trigone is the only portion remaining fixed after herniation. Five cases have been described in the literature reviewed affecting ureters. The present paper represents the fourth case of bilateral ureterohydronephrosis in the literature. The treatment is surgical correction of the inguinoscrotal hernia.

[Ectopic thoracic kidney].

We present a case of kidney ecthopy in a 62 years old male patient, discovered by chance during complementary explorations realized in the diagnostic process of an acute respiratory pathology. We review the literature related to this anomaly: 200 cases have been published to the date. The thoracic kidney is a rare kind of kidney ecthopy, tipically without synomathology & it requires no treatment.

Choristoma↗

[Primary signet cell adenocarcinoma of the bladder].

The primary signet-ring cell adenocarcinoma of the bladder is a rare tumor, with great biological aggressivity and bad prognosis. We report a clinical case of a 65 years old patient, starting with bladder irritative symptoms and suffering from advanced disease at the initial diagnosis. We review clinical and etiopathogenic aspects about this entity.

[Melanoma of female distal urethra: apropos of a case].

A case is presented of melanoma located at the distal urethra in a 74-year-old patient who underwent local surgery. At present the survival rate is 5 years and local relapse and metastases of one inguinal ganglion has been observed. The different clinical, diagnostic and therapeutic aspects of this neoplasia are discussed.

[Chromophobe renal carcinoma. Case report].

Human chromophobe renal cell carcinoma is an infrequent neoplasm, recently descripted (1985). It is very important to separate it from the renal cell carcinoma due to its better prognosis. Presentation of the clinical, radiographic and histological features of two cases of chromophobe renal cell carcinoma, diagnosed and treated in our Centre.
