Role of Ureteral Stenting in patients Undergoing Intra-Corporial Pneumatic Lithotropsy for Mid and Distal Ureteric Stone.
Pak J Med Health Sci Jan ;12(3):1123-5.

Background: It has been a popular and accepted surgical tradition to place a ureteral stent after performing ureterostomy especially when performing lithotripsy for ureteral calculi. However the use of stents is accompanied by significant morbidity including pain, infection, and irritative voiding symptoms. Aim : To compare the outcome of stented vs non stented patients after lithotripsy for ureteric stone Study design: Randomized control trial Setting and duration : Department of Urology / Jinnah Hospital, Lahore. Six month. Methodology : 250 subjects were included in our study and randomly divided into 2 groups. During procedure, Storzureteroscope with pneumatic lithoclast was used to fragment stones into pieces. Operative findings were noted down. After that, in Group A,6 Fr D.J stent was placed, while patients in group B was managed without DJ stent. Patients were followed up for 12 week. Outcome was measured in terms of postoperative pain, analgesia requirement and stone clearance. Results : Out of 250 cases (125 in each group), mean post-operative pain score at 12 weeks was recorded as 2.56 +/-0.55 in Group-A and 2.11 +/-0.61 in Group-B, comparison of stone clearance in both groups shows that 118( 94.4%) in Group-A and 116( 92.8%) in Group-B were had no stones, p value was 0.60, comparison of additional analgesia in both groups shows that 38( 30.4%) in Group-A and 13( 10.4%) in Group-B had requirement of additional analgesia whereas 87( 69.6%) in Group-A and 112( 89.6%) in Group-B no need of additional analgesia, p value was 0.0001. Conclusion : There was in significant difference in frequency of stone clearance and mean post-operative pain in stented v/s non-stented patients after URS and pneumatic lithotripsy for mid and distal ureteric stones.
