Urological injury and assessment in patients with fractured pelvis.

Of 200 patients with pelvic fractures 32 (25 male and 7 female patients) had urological injury. Of these 32 patients 31 had pubic ramus or symphyseal fractures: 29 had gross hematuria and a urine specimen was not obtained in 2. Only 1 of 77 patients with microscopic hematuria had serious urological injury. We believe that excretory urography is not necessary in all cases of pelvic fracture, and that urethrography and cystography are indicated only in cases of gross hematuria or when other clinical signs indicate a high likelihood of bladder or urethral trauma.

Experience with the Jonas penile prosthesis.

Between April 1981 and June 1983 the Jonas penile prosthesis was inserted in 57 patients. There were 10 early complications (17.5 per cent), with 8 operations for revision or removal (14 per cent). Late complications were rare and the over-all success rate was 96 per cent.

Cryosurgery in prostatic cancer: elimination of local lesion.

From 1969 through 1976, we performed cryosurgery in 229 cases of prostatic cancer. Most of these patients had bulky, locally extensive primary tumors, and one-half had disseminated disease. Through the open perineal approach, which gives exposure for an adequate freeze, cryosurgery has been well tolerated. The primary surgical goal has been to reduce or eliminate the local lesion to minimize subsequent cancer-related lower urinary tract problems and to cure those patients with truly localized disease. In every case cryosurgery produced dramatic shrinkage of the local lesion. After four to eight weeks a local recurrence was suspected in 13 per cent, and 41 per cent eventually had some evidence of a recurrent cancer nodule or persistent cancer in the bladder neck. In a series of statistical analyses we have related these recurrences to other clinical factors. Cryosurgery has been a safe, effective way to reduce or eliminate the primary prostatic cancer, even in patients with large local lesions.

Ureterovesical reflux in an adolescent and adult population.

The records and radiographic data on 177 adolescents and adults with vesicoureteral reflux were reviewed. The anatomic characteristics of 255 renal units and ureterovesical junctions were characterized using criteria reported previously. A total of 125 renal units demonstrated grades III to V reflux (International). Abnormal ureteral orifices were observed in 145 renal units and 155 submucosal tunnels were short or absent. Excretory urograms outlined renal scars in 192 renal units. Pre-treatment and post-treatment creatinine clearances were analyzed in 188 renal units. Ureteral reconstruction resulted in stabilization or improvement in the mean creatinine levels in 53 renal units. Other forms of surgical and medical treatment also resulted in improved renal function during observation.

Cryosurgery in prostatic cancer: survival.

From 1969 through 1976 we performed cryosurgery in 229 cases of prostatic cancer. This article presents survival in cryosurgery and other treatment groups. In every stage, despite a preponderance of large primary tumors and poor-risk patients, cryosurgery matched total prostatectomy and compared favorably to other modalities, including radiation therapy, at our center and elsewhere. According to previous authors, and in view of the present data, eradication of the local lesion is associated with better survival even in advanced cases. Cryosurgery provides a safe, effective method.

Tuberculous stricture of ureter.

Tuberculous stricture of the ureter is not uncommon in centers which treat large numbers of patients with urinary tuberculosis. Ninety-seven such strictures were seen in 92 patients over a twenty-five-year period. All patients were treated with appropriate antituberculous chemotherapy. Transurethral dilatation of the ureteral stricture was done on 80 ureters. Dilatation was successful in 51 ureters (64%) and failed to relieve the strictures in 29. Technical difficulties prevented dilatation of 17 ureters. We believe that transurethral dilatation should be attempted on all tuberculous ureteral strictures and that other procedures should be employed only if dilatation fails.

Congenital anomalies associated with cryptorchidism.

We reviewed 334 patients with cryptorchidism treated at our institution during a 13-year period. Other congenital anomalies were apparent on physical examination in 102 cases and these were more common in patients with bilateral cryptorchidism. Of the 205 excretory urograms done 25 showed abnormalities and, again, these abnormalities were noted more commonly in patients with bilateral cryptorchidism. Of 232 patients with asymptomatic cryptorchidism, that is with no other congenital findings on physical examination, 141 had an excretory urogram and 4 revealed some abnormality, 2 of these warranting surgical intervention. Of the 334 patients 16 had hypospadias and 50 were mentally retarded. The literature is reviewed. It is concluded that an excretory urogram is not justified on a routine basis in patients with asymptomatic cryptorchidism.

Renal carbuncle: diagnosis and management.

Six cases of renal carbuncle are presented. Nonstaphylococcal carbuncles now greatly outnumber those of staphylococcal origin. Diagnostic modalities are discussed. No radiologic or laboratory investigation is specific, but the diagnosis should be suspected in most cases if adequate attention is given the patient's signs and symptoms. Surgical treatment is recommended.

Penile prostheses for the treatment of impotence.

Eighty-nine patients were treated for impotence with penile prostheses. The Small-Carrion prosthesis was used in 56 patients, the inflatable prosthesis in 27 and Pearman's prosthesis in 6 patients. The overall functional results with the Small-Carrion and inflatable prostheses were comparable.

Nephrostomy in cancer patients: to do or not to do?

One hundred patients who have had nephrostomies performed for obstructive uropathy in the presence of extensive carcinoma have been retrospectively analysed. Patients with prostatic and cervical carcinoma had a moderately good long-term survival and quality of life, but those with bladder carcinoma or other primary sites had poor results. Significant factors in the selection of patients for nephrostomy drainage in the presence of pelvic cancer are discussed.

Urologic complications of pelvic exenteration for gynecologic malignancy.

We reviewed 43 cases of pelvic exenteration for gynecologic malignancies. Particular attention was paid to the postoperative urologic complications encountered in these patients. The major disease process was carcinoma of the cervix. Six patients had early postoperative complications and 2 of these patients died. Nine patients had late postoperative problems caused by urinary tract infections or stones. Nine other patients had problems related to the urinary diversion that necessitated a secondary operation in the majority of the cases and 2 of these patients died. Advantages of the ileal and colon conduits are discussed.
