[Penoscrotal gangrene: our series of cases].

Ten cases of penoscrotal gangrene seen in our department over the last 8 years are presented. In 80% of patients causative factors of the gangrenous process were demonstrated and were equally distributed between urology and colorectal pathologies. The most commonly associated pathology was diabetes mellitus affecting up to 50% of our patients. Two or more germs were isolated from the necrotic-purulent material for cultures, mainly E. coli (90%) and Proteus mirabilis (50%) as aerobic organisms, and Bacteroides fragilis (40%) in the anaerobic group. Despite emergency surgical therapy and high doses of broad spectrum antibiotics, mortality in our series was about 20%.

[Surgical treatment of urinary stress incontinence in women].

Long-term results obtained in 54 surgical procedures to correct effort urinary incontinence performed in 49 patients with this pathology are reviewed. One group was treated with suprapubic urethrovesical suspension with the Marshall-Marchetti-Krantz technique; the other group with endoscopic suspension of the neck of the bladder, with the Stamey technique and the third group with sling techniques. The authors conclude that any of the surgical techniques achieving a correct reposition of urethrovesical anatomy, rising the posterior urethra to its primitive anatomical bed, obtain a similar success rate.

[Directed chemotherapy in superficial carcinoma of the bladder conditioned by the knowledge of recurrence factors].

A retrospective study of 56 patients (23 primary and 36 relapsing) with superficial vesical carcinoma and treated with transurethral resection and directed chemoprophylaxis was done. Directed chemoprophylaxis is define as a specific type of adjuvant therapy where the drug is determined by a previous study with multivariant analysis of the relapse risk factors of a group of 385 cases, where the chemotherapeutic agent was also a variable. The drug is specified by the data introduced in a microprocessor program. Such chemoprophylactic approach has achieved a marked reduction in the relapse rate and increased the disease-free interval from 8 to 3 and from 70 to 83.5 respectively, with regard to the free drug choice approach.

[Calcification and contamination as complications in the use of double-J catheters: incidence and correlation].

We present a series of cases of complex renal lithiasis, in which we carried out temporary internal urinary bypassing, prior to extracorporeal lithotripsy, by means of the retrograde insertion of a double-J urethral catheter, studying the time of stay, the presence or not of contamination in the catheter and its relationship with the calcifications found in them. We also carried out a metabolic-functional study of each patient, determining the urinary pH and the serum and urinary calcium, phosphorous and uric acid concentrations, and observing their possible influence on the above-mentioned complications. Of the 25 catheters studied, we observed calcification in 11 cases (44%). In these we observed urealytic germs (Proteus and Pseudomonas), without finding modifications of urinary pH. We observed no relationship between the calcium deposits and serum and urinary calcium, phosphorous and uric acid concentration.

[Disseminated renal adenocarcinoma. Developmental study].

A study was undertaken on 57 patients diagnosed as having disseminated renal adenocarcinoma. The interval between the onset of symptomatology and diagnosis ranged from 1 to 48 months. The tumor frequently metastasized to lungs and bone. To evaluate survival, this patient population was divided into two groups: those who underwent nephrectomy, 17 patients (9 patients also underwent lymphadenectomy), and those who were put on drug therapy alone. No significant difference was observed with respect to survival for both patient groups.

[Percutaneous nephrostomy as a technic for emergency drainage: review of cases].

Percutaneous nephrostomy (PCN) is currently one of the procedures of choice for emergency drainage of the upper urinary tract. Moreover, it permits morphologic and functional diagnostic possibilities as well as a wide variety of new and frequently definitive therapeutic procedures. We report on 58 PCN procedures performed in 55 patients from May 1983 to February 1989. PCN was indicated for complicated or uncomplicated uni- or bilateral supravesical obstruction, with infection and/or azotemia. All patients submitted to PCN for complicated obstruction with infection and/or azotemia showed a marked clinical and analytical improvement. Apart from resolving this emergency, it reduced the morbidity and mortality rate of subsequent surgical treatment of the underlying cause of obstruction because patient status was markedly improved. The major complications, retroperitoneal hematoma and sepsis, were rare. We frequently observed that the catheter had come out or become obstructed in our series. PCN affords the following advantages: it can be performed with local anesthesia; it is a simple technique; there are no absolute contraindications; its morbidity and mortality rates are low; and, it can be easily converted into a permanent procedure. In our view, all the foregoing advantages, as well as its therapeutic and morphologic and functional diagnostic possibilities, make PCN one of the procedures of choice in emergency treatment of upper urinary tract obstruction.
