Abstract

Objective: Urinoma is a rare entity and mainly occurs due to acute obstruction such as ureteral stone. We aimed to demonstrate factors associated with urinoma accompanied by ureteral calculi.
Material and methods: Data of 550 patients who were diagnosed with ureteral stone by computed tomography (CT) were analyzed retrospectively. In 20 patients perirenal urinoma was associated with ureteral calculi (group I), whereas in other 530 patients no urinoma was detected (group II). Gender, age, size, side and localization of the stone, hydronephrosis, fever, sepsis, urinary tract infections (UTIs), hematuria, serum creatinine, blood urea nitrogen (BUN), white blood cell (WBC), C-reactive protein (CRP), presence of diabetes mellitus (DM), hypertension (HT) and cronic kidney disease (CKD) of the two groups were compared.
Results: The average age of the patients were 46.2 (20-71) and 44.9 (10-82) years in group I and group II, respectively (p > 0.05). According to our results leukocytosis, microscopic and macroscopic hematuria, UTIs, increase of serum creatinine, BUN and CRP, diagnosis of DM and HT were significantly associated with urinoma (p < 0.05). In addition, patients with distal ureteral stones are more prone to urinoma (p = 0.001). An interesting finding of the study was that the stone size in group I (median 5 mm [range 3-8]) was significantly smaller than in group II (9.3 mm [4-25]; p = 0.001).
Conclusions: Small stone size, distal localisation of the stone in ureter, leukocytosis, hematuria, UTIs, increase of serum creatinine, BUN and CRP, presence of DM and HT are associated with perirenal urinoma.
