Ureteral stent encrustation is a common problem, with incidence rates rising from 9% at 6 weeks to over 75% after 12 weeks of indwelling time. Objective: To determine the frequency and associated risk factors of the ureteral stent encrustation in patients with urolithiasis. Methods: This was a prospective descriptive study, conducted at the Department of Urology, JPMC, Karachi, Pakistan. All patients who visited to JPMC and fulfilled the inclusion criteria were included in the study after their consent. Stent duration was grouped into ≥ 6 weeks and < 6 weeks. The stent removal was done under general or local anesthesia. All the collected data were entered into the pre-defined study proforma. Results: Mean ± SD of age was 39.60 ±12.06 years. In the distribution of gender, 43 (58.9%) were male while 30 (41.1%) were female. Ureteral stent encrustation was noted in 11 (15.1%) patients. In the comparison of urinary tract infection and proteinuria, with and without ureteral stent encrustation was noted as 9.6% v/s 5.5% and 11% v/s 4.1%, and the p-value was found to be highly significant i.e., p < 0.0001. Conclusions: This study concluded that ureteral stent encrustation was prevalent in patients with urolithiasis. It is significantly associated with urinary tract infection and proteinuria. However, more prospective and well-controlled trials are needed to validate the current findings.
