Comparison of Extracorporeal Shock Wave Lithotripsy (ESWL) and Ultra-mini Percutaneous Nephrolithotomy (PCNI), in Renal Stones <20 mm.

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.

About this study

Even though small PCNL and ESWL are tried-and-true techniques for kidney calculus, their usage poses unique challenges since they need precision to guarantee effective stone removal while minimizing invasiveness. Despite these advantages, selecting the optimum course of action is challenging due to risks of both modalities. The results of this investigation would therefore help to improve the treatment of the patients with renal proximal stones that are smaller than 20 mm.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients of any gender
  • Aged 20-60 years
  • With a single kidney stone in renal pelvis smaller than 20 mm

Exclusion criteria

  • Pregnancy
  • Hemorrhage problems
  • Sepsis and pyonephrosis
  • With pelvic kidneys
  • Obstruction of the pelvi-ureteric junction
  • Chronic illness (chronic liver disease, chronic renal failure, chronic drug use)

Treatment and study plan

Ultra-mini PCNL

Procedure

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

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.

Primary outcomes

  1. Stone clearance

    Time frame: 4 weeks

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

  2. Urinary tract infection

    Time frame: 4 weeks

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