Ureteral hemangioma: a clinical case report.

The most greater part of the tumors ureteralis are of malignant nature, they are verified especially in the elderly patient and they have a preference for the distal third of the ureter. Of the tumors benign ureteral, the emangioma is a very rare vascular neoplasm. The symptoms aspecificis of presentation are: hematuria, colic type pains, hydronephrosis and bladder inflammation. Thanks to the refinement of the radiological techniques (Urography, CTscan and eventually the ascending pyelography) and also to the simultaneous aid of the anatomopathologist, it is possible to obtain an accurate description of this pathology in a precocious stage in order to carry out a conservative approach. The peculiarity of the clinical case from us described depends on the fact that it deals with an occasional find, reaches our observation for appearance of severe hydronephrosis caused by ureteral stones, resolved him with methodic endoscopic.

A case report of a "smouldering" uretero-vascular fistula.

Uretero-vascular fistulae are rare. As compared to aortic, uretero-iliac fistulae are by far more frequent according to a 1:8 ratio. We present one case of uretero-prosthetic fistula in a man operated upon the resection of an aortobisiliac aneurysm and Dacron prosthetic graft; six years later, a blunt trauma to the body was followed by a threatening shock, resistant to medical measures. Two subsequent emergency operations allowed to a difficult diagnosis and a life-saving repair of the fistula. Some hypotheses on the pathogenesis of the condition are discussed as well as its clinical problems.

A case of medullary sponge kidney (Cacchi-Ricci disease) mimicking a renal mass.

Medullary sponge kidney (MSK) is an uncommon benign congenital disorder, generally asymptomatic. In symptomatic patients the diagnosis is usually made by excretory urography performed in the most frequent complications such as renal stones, urinary tract infections and haematuria. Excretory urography can be very characteristic, showing cystic collections of ectatic collecting ducts like "bunches of grapes" or "bouquet of flowers". When haematuria represents the only symptom, and radiographic findings are not characteristic of MSK, the differential diagnosis with a renal tumor can be very difficult. We report a case of MSK that underwent nephrectomy since clinical and radiological features mimicked a renal tumor.

Randomized comparison of loops for transurethral resection of the prostate: preliminary results.

PURPOSE: To evaluate the comparative efficacy and morbidity of standard transurethral resection of prostate (TURP) and transurethral vaporesection (TUVRP) using four types of loops. PATIENTS AND METHODS: In a one-to-one randomized study, 50 patients with lower urinary-tract symptoms suggestive of bladder outlet obstruction and benign prostatic enlargement underwent TURP. Clinical data were collected using digital rectal examination, transrectal ultrasonography for evaluation of prostate volume, IPSS and IIEF-5 questionnaires, and serum prostate specific antigen concentrations. Intraoperative blood loss and fluid absorption were evaluated by measuring serum hemoglobin and respiratory alcohol concentration. Patients were followed at 3 and 18 months with evaluation of clinical symptoms, flow rates, residual urine volumes, and complications. RESULTS: There were no significant differences in blood loss, intraoperative fluid absorption, procedure time, or weight of the resected tissue between standard TURP and TUVRP with the various loops. No significant complications (infections, urethral stricture, reintervention) were seen. CONCLUSIONS: In this comparison of the clinical outcome and morbidity of standard TURP versus different loops for TUVRP, there were no significant differences in any of the parameters evaluated.

Bladder carcinosarcoma: a case observation.

Carcinosarcoma of the bladder is a very unusual neoplasm that arises more frequently in males with a greater incidence in the seventh decade of life. There are no patognomonic clinical findings or symptoms to address its presence. Symptoms, as for other bladder cancers, are fundamentally represented by haematuria and dysuria. It has a very aggressive clinical behaviour and it is histologically characterized by a malignant epithelial component associated with a sarcoma-like (sarcomatoid) component variably represented.

Bicalutamide monotherapy versus flutamide plus goserelin in prostate cancer: updated results of a multicentric trial.

OBJECTIVES: To compare the efficacy of bicalutamide monotherapy to maximal androgen blockade in advanced prostatic cancer. PATIENTS AND METHODS: Previously untreated patients with histologically proven stage C or D (American Urological Association Staging System) disease were randomly allocated to either bicalutamide (B) or goserelin plus flutamide (G+F). After disease progression, patients treated with B were assigned to castration. The primary endpoint for this trial was overall survival. Prostate cancer-specific survival and progression were included among secondary endpoints. RESULTS: In total 108 patients received B and 112 received G+F. At a median follow-up time of 54 months (range 1-89), 151 patients progressed and 113 died. There was no significant difference in the duration of either progression-free or overall survival. Hazards of progression, death and cancer-specific death, corrected by disease stage, tumor grade and baseline PSA level, showed that patients initially assigned to B had a higher risk of progression but a comparable risk of death and cancer-specific death with the exception of patients with G3 tumors who had an increased risk of death). CONCLUSIONS: In patients with well or moderately well differentiated tumors, B monotherapy followed by castration may offer the same survival chance as maximal androgen deprivation. In those patients it thus represents a reasonable choice that can avoid the side effects of androgen deprivation for considerable periods of time.

Massive hematuria after transurethral resection of the prostate: management by intra-arterial embolization.

A case of severe hemorrhage after TURP leading to hypovolemic shock and its successful management by superselective unilateral arterial embolization is described. The authors conclude that arterial embolization is a safe and effective procedure for severe prostatic hemorrhage that may be performed in selected cases when conservative means or fulguration of the prostatic fossa have failed to achieve the control of the bleeding. Adequate selection of the patients, correction of any underlying coagulation defects and a proper resection technique are surely the most important issues in preventing any postoperative bleeding.
