Ureteral stents have been widely used for more than two decades with different indications. Due to the widespread usage of ureteral stents, the number of possible complications of ureteral stents has increased, including stent migration, encrustation, stone formation, and fragmentation. Among these complications, ureteral stent fragmentation is rare. Herein, we present a case of spontaneous ureteral stent fragmentation and review the relevant literature.

Purpose The aim of the present randomized study was to evaluate the efficacy of lidocaine gel compared with dimethylsulfoxide (DMSO) with lidocaine for transrectal ultrasonography (TRUS)-guided prostate biopsy in patients with anorectal pathologies.Patients and Methods Sixty-two patients were randomly divided into two equal groups. Group 1 was given 10 mL of 2 lidocaine gel intrarectally 10 minutes before the biopsy. Group 2 was given 10 mL of intrarectal 40 DMSO with an amount of lidocaine equal to that in the lidocaine gel 10 minutes before the procedure. The degree of pain was rated by patients using a 10-point visual analog scale.Results The pain scores for probe insertion were significantly lower for group 2 (3.15 ± 1.41) than for group 1 (4.58 ± 160) (P 0.01). No significant differences were found between the pain scores of the two groups for biopsy-needle insertion (P 0.62).Conclusions Dimethylsulfoxide with lidocaine instilled into the rectum is a simple, safe, rapid-acting, and effective method of anesthesia delivery before TRUS-guided prostate biopsy in patients with anorectal pathologies.
