- Abstract
Purpose: To determine factors affecting patients' discomfort during the period self-retaining ureteral stentsare in place.Patients and Methods: Between April 2001 and May 2003, 58 male and 42 female patients underwent temporarydouble-pigtail stenting. The indications were endopyelotomy in 39 patients, ureteroscopy in 32, laparoscopicpyeloplasty in 18, and endoureterotomy in 11. The stents were silicone in 56 patients and Percuflexin 44. The median stenting period was 8 weeks (range 4–16 weeks). Patient discomfort was evaluated by aquestionnaire conducted by the physician before stent removal. Tested variables were patients' sex, side ofthe stent, urine culture, stent material, stent length and diameter, and stenting duration. The site of the uppercoil (renal pelvis or calix), the site of the lower coil (in the same side or crossing the midline), and theshape of the lower coil (complete circle or not) were also tested. Univariate and multivariate analysis werecarried out to determine significant independent variables, with P < 0.05 being significant.Results: Of the total, 59 patients experienced discomfort consisting of dysuria, urgency, urge incontinence,loin pain, suprapubic pain, frequency, nocturia, or gross hematuria or some combination. Significant factorsassociated with discomfort were a positive urine culture, crossing of the lower end of the stent to the oppositeside, caliceal position of the upper coil, and longer stenting duration.Conclusion: Proper positioning of the coils of the stent, eradication of infection, and shorter stenting durationare advised to decrease patient discomfort during the period of ureteral stenting.
