[Various echographic features in testicular torsion]. / I diversi aspetti ecografici nella torsione del testicolo.

The Authors discuss the informations that can be obtained from sonography in testicular torsion on the basis of 21 patients. The different sonographic features of the twisted testis, which are time-related, are reported and stressed. Ultrasonography is a very sensitive diagnostic tool and can be a useful complement of clinical examination.

[Rupture of the testicle: comparison of the echographic picture and operative findings]. / Fratture del testicolo: confronto fra quadri ecografici e reperti operatori.

9 patients suffering from testicular rupture, owing to blunt scrotal trauma, were examined with ultrasound and then underwent surgical exploration. Sonography correctly diagnosed testicular rupture in 8 patients, 1 false-negative occurred. Clinical examination often is difficult in evaluating testicular trauma, sonography provides a useful tool for improved diagnosis in testicular rupture.

Blind-ending branch of bifid ureter: report of seven cases.

Seven cases of bifid ureter with a blind-ending branch are presented: diagnosis was primarily made by excretory urogram. In 1 case the diagnosis was confirmed by retrograde pyelogram. The pelvicalyceal system showed ureteroureteral reflux into the blind-ending branch on photofluoroscopy and cineroentgenography. One rare case of blind-ending branch originating in the upper third of the ureter are described. The clinical aspects, roentgenographic findings, and treatment of these findings are reviewed.

Prevention and management of urinary tract infections following endoscopic and urological surgery using one dose daily of tobramycin.

The therapeutic activity of a single dose of 150 mg of tobramycin, parenteral administration, was studied in the prophylaxis of urinary tract infection (UTI) postoperative or postendoscopic. This study incorporated 85 patients of both sexes ranging in age from 18-91 years; 20 had had previous UTI. Duration of therapy ranged from 5 to 15 days and was determined by clinical response; 70 of 85 patients clinically observed achieved excellent results, 10 good and 5 moderate. In 5 cases persistent asymptomatic bacteriuria recurred, indicating incomplete eradication of the microorganism. Results of data showed the clinical efficacy, safety and tolerance of tobramycin, in one dose only, in the prophylaxis of UTI posturological surgery, as well as its easy administration and limited cost.

Recurrent reflux caused by vesicoureteral fistula.

We present an unusual case of recurrent reflux on the right side after bilateral vesicoureteroplasty with modified Hutch I technique.

[Radiological evolution of renal pelvis tumours (author's transl)]. / Quadri evolutivi delle neoplasie pielo-caliciali.

The tumours of renal pelvis show a polymorphic radiological pattern, often rather difficult to interpret, sometimes even not evident owing to the presence of some other pathology. The most characteristic cases, and to be considered specimen, found in researches executed at different times, are represented by carcinomas, among which the ones showing the most elevated histological malignancy present a more rapid and infiltrative growth, as testified by repeated radiological tests.
