Tumors of the spinal cord present as a rule with posterior pain with or without radiation to the limbs, with loss of strength and/or sensory disturbances. We report a case in which acute retention of urine was the only presenting symptom.
This is a report on a case of 2 concurrent neoplasms of different histology within the same kidney: a renal cell carcinoma and a transitional cell carcinoma of the renal pelvis in a patient affected by chronic renal failure due to abuse of phenacetin. There was also a transitional cell carcinoma of the urinary bladder.
We studied bladder and urethral function prospectively in 64 patients before and after Wertheim's radical hysterectomy. Immediately after surgery, neurogenic bladder dysfunction of various degrees was found in 70% of all patients who presented difficulty of voiding, with high residual urine and/or stress incontinence. All the patients have received an early rehabilitative treatment with kinesitherapy and/or pharmacological therapy after the bladder catheter removal and the urodynamics' results. We have obtained a satisfactory functional recovery of the bladder activity in 91% of the symptomatic patients.
We prospectively studied bladder and urethral function in 44 patients before and after abdominoperineal resection of the rectum for ano-rectal cancer. The patients were investigated with the following examinations: combined cystometry and electromyography, urethral pressure profile measurement, urecholine denervation test, urine culture, urethrogram and residual urine measurement after voiding. Urodynamic results after surgery demonstrated the partial or total denervation of the detrusor muscle with bladder areflexia in the 54% of the cases, the decrease in the urethral pressure profile in the 48% of the cases, and the absence of detrusor sphincter dyssynergia in all cases. Urethrogram results showed a high incidence of bladder dislocation into the presacral space (36%). Urine cultures were frequently positive in 52% of the patients. Most patients (52%) had difficulty in voiding with high residual urine and/or stress incontinence (4.5%). All the patients received an early rehabilitative treatment with kinesitherapy and/or pharmacologic therapy after bladder catheter removal and after urodynamic results. The patients with neurogenic bladder with residual urine volume had satisfactory functional recovery of the activity.

The efficacy and safety of aztreonam in the prophylaxis of urinary tract infection following transurethral resection of the prostate (TURP) in patients with preoperatively sterile urine were studied in a multicenter trial including 300 patients at six Italian urology centers. The present report describes the first 192 patients enrolled in the protocol. Aztreonam or placebo was administered to each patient in three doses, which were given at the induction of anesthesia and 8 and 16 hours later. The development of bacteriuria was monitored by cultures of urine obtained before surgery, 3 days later, at removal of the bladder catheter, at discharge from the hospital, and at a follow-up visit 39-46 days after surgery. A febrile peak was observed for 6% of aztreonam-treated patients and for 20.9% of the placebo group (P less than .005), while bacteriuria was reported in 17.9% and 59.3% of these groups, respectively (P less than .001). From our data, TURP appears to be a clean-contaminated procedure requiring antibiotic prophylaxis, and aztreonam appears to reduce significantly the incidence of postoperative bacteriuria after this surgical procedure.

AIMS AND BACKGROUND: Neoadjuvant systemic chemotherapy in infiltrating transitional cell carcinoma of the bladder has proved to be effective and to provide a pathologic complete response in about 30% of patients. No survival benefit has yet been proved. METHODS: We analyzed the outcome of 75 patients with advanced bladder cancer (stages T2-T4 N+/N0 M0) treated from 1985 to 1993 at two institutions in the same geographic area with 2 or 3 cycles of neoadjuvant CMV (cisplatin, methotrexate and vinblastine) chemotherapy plus cystectomy. Transurethral resection of the tumor was expressly avoided in order to keep the tumor intact as a marker lesion to evaluate response to chemotherapy. RESULTS: At the time of analysis, the median follow-up of 67 assessable patients was 51.5 +/- 3.9 (SE) months. Forty-six patients (69%) had clinical evidence of extravesical spread of the bladder tumor and 6 of lymph node metastases at presentation. After cystectomy, a pathologic complete response (pT0, pN0) was achieved in only 6 cases (9%) and a pathologic partial response in 32 patients (48%). The overall 5-year survival rate of all patients was 61 +/- 6%. Those patients who had a major response to chemotherapy (pCR +pPR) had a 5-year disease-free survival rate of 74%, which was statistically higher (P = 0.0021) than the 44% for the remaining nonresponding patients (pNR). Overall, 43% of the patients with stage T2-T3a disease achieved tumor downstaging (CR, 5%; PR, 38%) compared with 63% of the patients with T3b-T4 (CR, 11%; PR, 52%), although there was no significant difference in 5-year survival curves between the two groups. CONCLUSIONS: A pathologic complete response was achieved in less than 10% of the cases without a preoperative tumor resection. Unfortunately, most of the responses were only partial. Even though the study appears to suggest a survival advantage for those patients who achieved a downstaging, CMV chemotherapy had a limited curative potential in most of the patients. It seems unlikely that determinant proof will be obtained that neoadjuvant chemotherapy may improve survival over a nontreatment control arm. The intrinsic chemoresistance or the suboptimal response to chemotherapy of bladder cancer remains the most adverse prognostic factor.
The Aarskog syndrome is characterized by short stature, hypertelorism, cryptorchidism, typical scrotal fold, clinodactyly and brachydactyly. From the available data the prognosis about definitive stature and fertility is good. In our case the anomalies of the testis are severe and we think that infertility is probable.

A case is reported of intrauterine spermatic cord torsion. The authors underline the necessity for checking infants' genitalia carefully during postpartum examination. Spermatic cord torsion, during intrauterine life, often involves both testes and therefore early treatment must be initiated to avoid functional anorchia.
