The aim of the study was to investigate the morphology of mesothelial cells of the peritoneum of patients with terminal renal failure (TRF), taken by the biopsy immediately before the onset of peritonal dialysis (PD), and to compare it with the findings in patients with PD. The samples were prepared in the way standard for light microscopy and transmission electron microscopy. In patients with TRF intracytoplasmatic inclusions could be observed, unusual protrusions of mesothelial apical surfaces, deformation of mesothelial cells and their detachment from the basal membrane, as well as the dilatated cisternae of granulated endoplasmatic reticulum with filamentous structures in some of them. In patients on PD cytoplasmic protrusions of different shapes and contents were observed at the surface of mesothelial cells, multiplication of basal membrane, occurrence of young forms of mesothelial cells as well as the detachment of those cells from the basal lamina.

Ureteral fistulae after kidney transplantation represent major early urological complications with reported incidence from 1.2% to 12% in large series. The aim of the study is to establish the incidence, types and ureteral fistula related morbidity and lethality rates, by donor type. From 1995. to 2001, a total of 224 kidney transplantations (171 from living and 53 from cadaveric donor) have been performed at the Institute of Urology and Nephrology in Belgrade. Mean patients age was 36,67 years (11-64; SD = 10.69). Ureteral fistulae appeared only after living donor transplantation in a total of five patients (2.2%) (p > 0.05). In all patients open fistula repair was performed. Two patients had recidive ureteral fistula after primary and after secondary open repair. Following the third open repair one patient had lethal outcome. Ureteral fistulae after kidney transplantation still remain challenging urological problem with considerable morbidity and lethality rates.

In minority of renal transplants it is unevitable to perform atypical vascular procedures of renal allograft implantation, which increases the risk of vascular complications, graft loss and lethality. In the presenting study, we retrospectively evaluated kinds of atypical vascular procedures in renal allograft implantation by donor type and the transplants outcome related to these procedures. From 1980 to 1998, a total of 463 patients (mean age 36.2+/-10.3), underwent renal transplantation (319 from living donor and 144 from cadaveric donor) at the Institute of Urology & Nephrology in Belgrade. Atypical vascular procedures of renal allograft implantation were representative for the some of the following cohorts: bypass grafting, endarterectomy, end to side both arterial and venous anastomotic site. A total of 45 patients (9.72%) underwent some of atypical vascular procedures (41 from living donor and 4 from cadaveric donor) (p<0.01). Among analyzed procedures, bypass grafting was performed in majority of cases (n=38). A total of 101 patients underwent endarterectomy. End to side both arterial and venous anastomotic site was done in two patients. Severe direct postoperative vascular complications following by lethal outcome appeared in 2 patients. Related to standardized, atypical vascular procedures had been of increased risk for appearance of severe vascular complication.

Fracture of the penis, or rupture of the corpus c avernosum is an uncommon injury, but probably under-reported entity. Only approximately 180 cases have been reported in the literature. Penile fracture with urethral injury is even more uncommon, accounting for approximately 10 to 20% of the cases reported. Early reports on this injury suggest conservative therapy as the choice of treatment. Recent reports emphasize immediate surgical repair to prevent late sequelae of injury, especially those associated with urethral rupture. We review 5 cases with evaluation, treatment and followup. Delays in treatment lead to long-term complications.
