Introduction. Urinary stasis in transplanted kidney occurs due to ureteral
obstruction caused by intrinsic or extrinsic etiological factors. The aim of
this study was to determine the prevalence, time of occurrence and
etiopathogenetic factors of urinary stasis and their distribution according
to the type of kidney donor. And to analyze the success of different types
of surgical and conservative treatment. Methods. The
retrospective-prospective randomized study included 580 patients
transplanted in Transplant Center, Clinic of Urology, Clinical Center of
Serbia for a period of 20 years. After diagnosing urinary stasis, minimally
invasive or open surgical interventions were performed, while for one group
of patients the definitive treatment was non-surgical with observation and
active monitoring. The main control parameters during non-surgical treatment
were diameter of pyelon, serum creatinine values and urine culture findings.
Results. Urinary stasis was found in 15% of transplanted patients. The
largest number of transplanted patients had early urinary stasis, within 3
months of transplantation (68%). The most common etiological factors of
urinary stasis were intrinsic factors (66%), which were significantly more
frequent in transplant patients from a living donor. Non-surgical treatment
with observation and active monitoring was successfully performed in 22% of
patients. Conclusion. The largest number of transplanted patients with
urinary stasis has been successfully treated surgically, most often with
open surgery. Surgical correction is advised in cases of pronounced
dilatation of the canalicular system with a tendency to increase, in
progressive decrease in renal function and recurrent complicated urinary
infections refractory to antibiotic therapy.
