High retroperitoneal lymphocele: unusual clinical presentation and diagnosis by ultrasonography.

A case of a mid lumbar lymphocele secondary to retroperitoneal lymphadenectomy for testicular carcinoma is described. The clinical picture was unusual and confusing in that the symptoms were gastrointestinal in nature. Ultrasound provided the diagnosis and guidance for aspiration. Although the most common operative source of lymphocele formation appears to be the pelvic lymphatics similar collections may arise from para-aortic and renal hilar dissections and produce unusual manifestations. Ultrasound is of established value in such cases.

Comparison of serum and prostatic levels of tobramycin.

Tobramycin sulfate, an aminoglycoside antibiotic, has been shown to be effective in the treatment of complicated urinary tract infections. Because of this, a study was undertaken to determine the penetrance of tobramycin into the prostate gland. It was found that the drug is concentrated at inhibitory levels in the prostate gland after the routinely recommended administration and should be useful in the treatment of bacterial prostatic infection.

Epididymitis in infancy.

The occurrence of epididymitis in infants suggests the presence of urinary infection and the likelihood of an associated structural genitourinary abnormality, requiring complete urologic investigation. The advent of testicular scanning and the ultrasonic stethoscope, coupled with an increased index of suspicion, makes possible the non-operative diagnosis and management of a condition usually made by surgical exploration.

Evaluation of closed suprapubic cystostomy.

Closed suprapubic cystostomy is an expeditious procedure for a variety of clinical conditions requiring urinary drainage. Its benignity is reflected by a low complication rate of 1.6 per cent and no deaths in this series of 244 consecutive patients. Nevertheless, major complications can occur if proper technique is not adhered to or contraindications are not observed.

The association of significant renal anomalies with Turner's syndrome.

The incidence of significant renal anomalies in 38 patients with Turner's syndrome was 26 per cent (10 of 38 cases). An additional 11 per cent of the patients have insignificant renal abnormalities and 63 per cent apparently have normal excretory urograms. In this series there seemed to be no correlation of the incidence of abnormalities with either the phenotypic or karyotypic expression of Turner's syndrome, that is the 45/XO pattern of the mosaic variants. Therefore, clinicians should be aware that any patient with Turner's syndrome must receive a thorough clinical and radiologic evaluation of the urogenital tract.

Ureteroileocancerous backflow: a diagnostic radiographic sign for metastatic carcinoma.

Ureteroileocancerous backflow is a radiographic finding representing extravasation of contrast material into venous sinuses of periureteral cancerous tissues. It is suggested that this finding, which has heretofore been undescribed, is diagnostic of recurrent malignancy and that patients may be spared secondary surgical procedures for confirmation of recurrent tumor.

Cefazolin and cephalexin levels in prostatic tissue and sera.

A study was carried out on 18 patients given cefazolin intramuscularly and 17 patients given cephalexin by mouth preoperatively prior to transurethral resection of the prostate. Prostatic tissue and serum levels of the two drugs were determined and contrasted with previously reported mean inhibitory concentrations. It was found that cefazolin was present in the sera and prostatic tissues in levels greater than was cephalexin and that cefazolin frequently exceeded the minimum inhibitory concentrations necessary for sensitive organisms to be affected, whereas cephalexin did not. Therefore, it would appear that cefazolin would be preferable to cephalexin in treatment of acute bacterial prostatitis.

Leiomyosarcoma of renal vein.

Primary leiomyosarcoma of the renal vein has not been previously reported in the urologic literature. A case report with long-term survival is described and the literature reviewed.

Urologic manifestations of polyarteritis nodosa.

Polyarteritis nodosa is an unusual condition that infrequently presents with signs and symptoms essentially confined to the urinary system. Such a case necessitating bilateral nephrectomy owing to hemorrhage is described. The pathologic findings, pathophysiology and etiology of the condition as well as treatment by renal transplatation are discussed.

Normal size of the urethral meatus in boys.

Statistically valid sizes have been obtained for the normal male urethral meatus in children from 6 weeks through 12 years old. It is hoped that these values will allow the diagnosis of meatal stenosis to be made on an objective rather than a clinical basis and that such evaluation will allow for a more rational approach to the therapy of meatal stenosis in boys.

A clinical evaluation of a screening (Microstix) for urinary tract infections.

The effectiveness of a screening device for urinary tract infection (Microstix**) was compared to routine laboratory cultures, sensitivities, and colony counts. The Microstix were highly effective in determining the presence or absence of urinary tract infections. In addition, they could be subcultured to provide meaningful bacterial sensitivities. Microstix are economical, easy to use, and accurate. Their use in the diagnosis and follow-up of urinary tract infections is therefore recommended.
