Abstract |
Ten cases of urinary calculi after renal transplanta- tion were reviewed retrospectively. Calculi occurred in 7 male and 3 female patients, 7 patients were recipients of living related and 3 of cadaveric kidneys. Calculi were diagnosed as early as 2 months and as late as 3.5 years after transplantation, but most were detected within the first year. The location of the calculi was the bladder in 4 cases, the transplant in 3, and indeterminant in 3. Crystallographic analysis of retrieved stones revealed calcium oxalate and/or phosphate in 4 cases, triple phosphate in 2, and uric acid in 2. All patients had one or more stone-predisposing factors, such as obstructive uropathy and recurrent urinary tract infection (4 cases), hyperoxaluria (3), or hypercalciuria (2). During long- term folow-up (mean 60 months), only one patient lost the renal graft, 14.5 years after transplantation, primar- ily from causes unrelated to urinary calculi. One ins- tance of stone recurrence was noted. |
