Brief Summary

There is a dearth of information comparing ultra-mini PNCL with ESWI in Pakistan for kidney stones smaller than 20 mm. Hence the current study was planned with the objective of comparing the outcome of ESWL and ultra-mini PCNL in renal stones less than 20 mm.

Conditions

Renal Calculi

Outcome Measures

Primary Outcomes (2)

• Stone clearance

  The frequency of the patients with full stone clearance was noted and cmpared between the groups.

  4 weeks

• Urinary tract infection

  The frequency of patients reported with urinary tract infection was noted and compared between the groups.

  4 weeks

Study Arms (2)

Group-A

EXPERIMENTAL

Patients were treated with ultra-mini PCNL with double J stent implantation.

Procedure: Ultra-mini PCNL

Group-B

EXPERIMENTAL

Extracorporeal shock wave lithotripsy (ESWL) with double J stent implantation was performed in patients. Typically, the therapy began with a lower power of 1 kilovolt (kV) and was progressively increased to 20 kV. Each session included no more than 2000 shocks.

Procedure: Extracorporeal shock wave lithotripsy

Interventions

Ultra-mini PCNL PROCEDURE

Patients were treated with ultra-mini PCNL with DJ stent implantation.

Group-A

Extracorporeal shock wave lithotripsy PROCEDURE

Extracorporeal shock wave lithotripsy (ESWL) with DJ stent implantation was performed in patients. Typically, the therapy began with a lower power of 1 kV and was progressively increased to 20 kV. Each session included no more than 2000 shocks.
