Abstract

Background: Urinary calculi are the third most common affliction of the urinary tract, exceeded only by urinary tract infections and pathologic conditions of the prostate. This study was carried out to assess the safety, efficacy and compare structural and functional outcome after treating the patients of upper ureteric calculus with Extracorporeal Shock Wave Lithotripsy (ESWL) and Ureterorenoscopy (URS).


Methodology: A prospective study was conducted on patients with upper ureteric stone of size 0.5 to 1.5 Cm. A total of 50 patients were included in the study by means of systematic random sampling so as to get 25 patients in each category of Extra Corporeal Shock Wave Lithotripsy (ESWL) and Ureterorenoscopy  (URS) for the treatment of their upper ureteric calculi.


Results: The age ranged from 15 years to 55 years. There were 36 males and 14 females in the study of 50 patients, 43 (86%) presented with pain followed by 4 (8%) presented with hematuria. 28 (56%) of the patients had stone in the range of 0.5Cm to 1.0Cm, 22 (44%) of the patients had stone in the range of 1.0 to1.5Cm. 16 (32%) patients had stone within 2 Cm of the PUJ, 13 (26%) had stone within 2 Cm of the sacroiliac joint. 21 (42%) patients, had stone in between these two. Of the 50, 25 patients (50%) underwent shock wave lithotripsy, 25 patients (50%) underwent URS.


In the ESWL group, 21 (84%) patients were stone free after single sitting of ESWL. 4 patients (16%) who required Re ESWL, after repeat ESWL two became stone free however 2(8%) patient of 1.0-1.5 Cm category required secondary procedure i.e URS and became stone free. To achieve stone free 1.24 procedure was required per patients. Of the 25 patients in the ESWL group, 2 (8%) patient (one steinstrass case and one poor fragmentation case) required secondary procedure. They underwent URS. Both the patient belonged to 1.0-1.5 Cm group. Ureterorenoscopy was done using semirigid ureteroscope by using pneumatic lithoclast. In our study, 2 patients of each 0.5-1.0 Cm and 1.0-1.5 Cm category did not become stone free. These four patients were subjected to ESWL and became stone free.


Conclusion: The management of the ureteral stone should be decided on individual basis, based on stone size, location, symptoms, obstruction and the availability of the instruments. For stones of 0.5-1.0 Cm, ESWL is the treatment of choice for upper ureteric stones, with very low Re-ESWL (1.12 sittings) without any requirement of ancilliary procedure. URS may be used for upper ureteric stones but requirement of ancilliary procedure is high 11.11%. For stones between 1.1 cm  to 1.5 Cm, ESWL is the preferred modality of treatment for upper ureteric stones.
