We reported two cases of nephrotic syndrome associated with hydronephrosis. A forty four year old male patient who suddenly complained of nephrotic syndrome, showed left hydronephrosis caused by lower ureteral stenosis. Renal biopsy specimen obtained from the right kidney revealed minor glomerular abnormalities. A sixteen year old female patient had a long history of proteinuria before the onset of nephrotic syndrome. She suffered from bilateral hydronephrosis of which the etiology was unclear. Renal biopsy specimen obtained from the left kidney revealed membranous nephropathy. Because in both cases urine samples collected from each ureter showed the presence of a massive protein, the other kidney was thought to be involved with the same disease. The association of nephrotic syndrome with hydronephrosis is extremely rare. The significance of this unusual combination was discussed with respect to the literature.

8 cases of membranous glomerulonephritis (MG) after renal transplants (RT) are presented; one being a recurrence of the original disease and the other 7 due to a different cause of renal insufficiency. The total incidence of MG after transplantation was 1.63%; 1.39% being the incidence of MG of new cases. Only 1 patient showed decrease of renal function and in this case the MG was accompanied by chronic rejection lesions. There was no sign of neoplasias nor drugs producing MG. As far as chronic infections are concerned, only one patient showed B antigen and it was not observed during the immunofluorescent test in the biopsy. 6 patients had urological complications after the renal transplant (3 cases of urinary fistula; 2 cases of obstructive uropathy; 1 case of short ureter). 2 patients experienced the start of hemodialysis due to focal and segmentary glomerulosclerosis. The beginning of proteinuria commences between 2 and 23 months after the RT (median 13,0 +/- 7,5 moths); with a range of between 2.0 and 12.0 gr/day (median: 6.8 +/- 3,2 Z gr/day), this being nephrotic in 4 cases. Proteinuria improved 1 case, and persisted in the other patients at the same level registered previous to the diagnosis. MG is a non-frequent complication or RT and is usually benign. Patients with post-transplant urologic complications could be considered to have a higher risk of developing a MG "de novo".

A 54-year old man received a cadaveric renal allograf for end-stage renal disease due to membranous nephropathy. The patient developed scrotal oedema, 14 days after renal transplantation. The biochemical analysis of scrotal fluid after surgical drainage demostrated urine. Helical computed tomography was performed and it showed contrast leaks in medial, distal ureter and bladder. The urinary fistula was treated with surgical repairment and catheter endoluminal of ureter which was retired in four weeks. The incidence of urinary fistula ranged from 3 to 9%. The scrotal or perineal oedema is unusual clinical presentation of urinary leaks. The diagnosis of urinary fistula may be difficult and depends on a high degree of clinical suspicion. The helical computed tomography is a technique which allows a high resolution three-dimensional reconstruction and it can be used to make the diagnosis of urinary fistula.
