Abstract: This study was performed to evaluate the lower urinary tract symptoms in patients undergoing pigtail suture stent (PSS) fixation and compare it with LUTS due to traditional (JJ) stent. PSS stent has been used since December 2010 in 295 patients. In this innovative PSS, the lower part of the stent is replaced by a 0.3F thread of suture. Only the renal and ureteral parts of the stent are retained and are extended by a thin tail ending in a suture. Whether the obstruction is due to a stone, an ureteropelvic junction syndrome, or ureteral stenosis, the upper, unmodified part of the stent facilitates the passage of urine around the obstacle. The study included 40 patients had ureteric obstruction (stone or stricture) divided randomly in to two groups, each group containing 20 patients, 1st group subjected to PSS fixation, other group subjected to JJ stent fixation. Lower urinary tract Symptoms were evaluated with a validated symptom specific questionnaire (International Prostate Symptom Score) (IPSS) in both groups. It is concluded from the previous observations that the PSS significantly decreases urinary symptoms and pain scores and constitutes a medical advance in the domain of ureteral stent tolerance.
