Efficacy and safety of TachoSil as haemostatic treatment versus standard suturing in kidney tumour resection: a randomised prospective study.

Objective: Elective nephron-sparing surgery (NSS) for renal cell carcinoma (RCC) has gained general acceptance as an alternative to radical nephrectomy. To achieve haemostasis without risk of local ischaemia and necrosis of kidney parenchyma after standard haemostatic suturing, we investigated TachoSil's efficacy and safety as atraumatic haemostatic treatment after kidney tumour resection.

Methods: A total of 185 patients scheduled for NSS for small, superficial kidney tumours were included in an open, randomised, prospective, multicentre, parallel-group trial.

Multiphasic helical CT of the kidney: increased conspicuity for detection and characterization of small (< 3-cm) renal masses.

Purpose: To evaluate the potential of thin-section multiphasic helical computed tomography (CT) in the detection and characterization of small (< 3.0-cm) renal masses.

Materials And Methods: Identically collimated helical CT of the kidney was performed before and after administration of contrast material in 93 patients with small renal masses.

Effect of extracorporeal shock wave lithotripsy on prostate specific antigen.

Purpose: We evaluated the effects of extracorporeal shock wave lithotripsy (ESWL) of distal ureteral calculi on serum prostate specific antigen (PSA).

Materials And Methods: A total of 29 consecutive men with distal ureteral calculi at a maximum of 25 mm. from the ureteral orifice, and without any history of urinary tract infection, benign prostatio hyperplasia or prostate cancer underwent ESWL with the Dornier MPL 9000 X lithotriptor.

[Nephrogenic adenoma after kidney transplantation].

We report five cases of nephrogenic adenoma that arose several years after cadaver kidney transplantation. Cystoscopy was performed in all patients because of gross haematuria and revealed multifocal tumorous lesions in all parts of the bladder. On admission to of hospital graft function was satisfactory in all patients.

[Erectile dysfunction in patients with type I diabetes mellitus].

To improve diabetes care according to the St. Vincent Declaration an interdisciplinary working group on erectile dysfunction in patients with diabetes was installed in the Departments of Internal Medicine, Urology and Psychiatry at the University of Graz. The screening and basic diagnostic procedures are performed in the diabetes clinic in the Department for Internal Medicine.

Laparoscopic procedure for varicocelectomy.

Objective: To report the results of laparoscopic varicocelectomy, a new surgical technique which presents minimal risks and provides an effective management of clinical varicoceles.

Patients And Methods: Between July 1991 and November 1992, 45 laparoscopic varicocelectomies were performed in 44 patients whose ages ranged from 11 to 41 years. Endoscopic ligation, carried out according to the technique described by Palomo, was performed in 14 patients.
