BACKGROUND In patients with end-stage renal disease, cholelithiasis is observed with an increased frequency. In transplant recipients, symptoms might be obscured, which may delay the diagnosis and lead to complications. The aim of our study was to evaluate the frequency of gallbladder pathologies in kidney transplant recipients (KTRs) in the Caucasian population, and to discuss the potential benefits of prophylactic cholecystectomy before kidney transplantation (KT). MATERIAL AND METHODS Data from 434 patients who underwent KT was analyzed. Demographic data along with gallbladder status were collected from the pre-transplantation charts. We compared our results to data from the general Polish population. RESULTS In our analyzed group of KTRs, there were 284 men and 150 women. Complete data, including abdominal ultrasound description, were available in 412 cases. In this group, 36 patients (8.74%) underwent cholecystectomy before KT. Other gallbladder pathologies (gallstones and polyps) were found in 41 patients (9.95%) at pre-transplantation evaluation. The incidence of gallbladder pathologies in KTRs, being mostly cholelithiasis, was higher than in the general Polish population. CONCLUSIONS In specific age subgroups of KTRs, the frequency of gallbladder pathologies was higher than in the general population. Prophylactic cholecystectomy may potentially offer benefits in these subgroups of patients.
