Is There an Adjunctive Role of Tamsulosin to Extracorporeal Shockwave Lithotripsy for Upper Ureteric Stones: Results of an Open Label Randomized Nonplacebo Controlled Study

Objectives

To investigate the role of tamsulosin as an adjunct to management of upper ureteric stones (UUS) with extracorporeal shock wave lithotripsy (SWL).

Methods

In this prospective, randomized, open label study, patients with single UUS (for SWL) were randomly assigned into 2 groups based on whether they received 0.4 mg tamsulosin (group A and B, respectively) during treatment. Repeat SWL was performed at week 1, 3, and 5 after first session. Primary outcome variables were success rate and pain intensity.

Results

A total of 40 patients (20 each group) completed the requisite follow-up. Success rate was higher in group A after 1 SWL-session (55% vs 25%, respectively; P = .05). There was an insignificant trend of decreased number of days (30.7 ± 19.7 vs 39.0 ± 19.9; P = .19), number of SWL sessions (1.6 vs 2.0; P = .10), and pain experienced (score on visual analog scale, 25.3 ± 17.9 vs 38.3 ± 28.0, respectively; P = .41) in group A. Three in group A and 6 in B developed steinstrasse (P = .69). Overall, 1 in group A required auxiliary procedures as compared with 3 in control group (P = .60).

Conclusions

Tamsulosin improves clearance rate of UUS after single SWL. However, it does not provide significant advantage in terms of decreasing pain associated with this treatment.
