Transurethral cystolithotripsy for large vesical calcul.
Esculapio J Services Inst Med Sci Jan ;9(1):1-3.

Objective: To assess efficacy and safety of transurethral cystolithotripsy in the management of large vesical calculi. Material & Methods: Adult patients with large vesical calculi (>2.5cm) were selected for this prospective study. Patients with associated urethral stricture and big adenomas were excluded. Stone size was measured on ultrasound in the largest diameter. Patients were operated under spinal or general anaesthesia. Nephroscope with 28 fr sheath was used transurethrally along with 2 cm lithoclast probe. Initial fragmentation was achieved with Swiss lithoclast. Later bigger fragments were dealt with stone punch. In the end all fragments were evacuated with Ellick evacuator. Bladder was drained with Foley’s catheter for 24 hours. TURP (transurethral resection of prostate) was done if required. Patients with bigger glands were excluded to restrict operating time. Patients were followed up for two weeks. Results: Forty patients were selected. Mean age of the patients was 55 years (range 18-73 years). There were 32 males (80%) and 8 females (20%). Stone size was 4.72+ 2.52 cm with range of 2.5-7.0 cm. Five patients had multiple stones, four of them had associated neurogenic bladder. Procedure time ranged from 20-90 minutes (mean 45.8 minutes). Complete fragmentation of calculi was achieved in all patients. Twelve patients underwent TURP under same anaesthesia. Time consumed on resection of prostate was not included in procedure time. There were no major complications. Conclusion: Transurethral cystolithotripsy is very effective and safe for large vesical calculi (>2.5cm). It is time consuming but saves patients from hazards of open surgery.
