TRANSURETHRAL NEPHROSCOPIC FRAGMENTATION OF LARGE URINARY BLADDER CALCULI USING PNEUMATIC SWISS LITHOCLAST

ABSTRACT
Objective: To assess the out-come of Transurethral Nephroscopic Cystholithotripsy using pneumatic Swiss lithoclast
in treatment of large urinary bladder calculi.
Material and Methods: This descriptive prospective study was conducted in the Institute of Kidney Diseases, Hayatabad
Peshawar from January 2014 to May 2017. In this study we included all those patients with bladder stone size
3 cm or more assessed by pelvic ultrasonography and x-ray pelvis. Patients with bladder stone less than 3cm, age
less than 25 years, previous bladder neck surgery were excluded. The outcome regarding stone clearance, length of
procedure, any intra-operative complications were noted down in preformed proforma.
Results: A total number of 34 patients fulfilling the criteria were included in this study. There were 32 males and 2
female patients, and male to female ratio was 16:1. Mean age was 52.5years;mean stone size was 42.46mm. Stone
clearance rate was 94.1%. In 2 (5.8%) patients, the procedure was abandoned due to bleeding. mean length of procedure
was 55 minutes.
Conclusion: Transurethral nephroscopic cystholithotripsy with pneumatic Swiss lithoclast is a safe and effective procedure
for the treatment of patients with large bladder stones.
