Comparative study of percutaneous cystolithotripsy vs transurethral cytolithotripsy

Abstract

Background: Bladder stones are common and, in most cases, occur in adult men with bladder outlet obstruction.The aim of the study was to compare transurethral cystolithotripsy (TUCL) and percutaneous cystolithotripsy (PCCL) modalities performed in management of patients with large vesical calculus at our super-specialty hospital

Material and Methods: The present comparative study was conducted in 40 patients randomly dividing into two groups of 20 each for two years on those who had vesical calculus of size more than 3 cms. In the 1st group, patients underwent percutaneous cystolithotripsy (Group I), while in the 2nd group (Group II); transurethral cystolithotripsy was done.

Results: Mean age, gender of the groups were similar. Mean aggregate stone sizes were significantly larger in the PCCL group. The operative time for stone removal was significantly less in the PCCL group. Also, mean urethral entries (minutes) was significantly lower in PCCL. Mean catheterization time was significantly lesser in Transurethral. Hospital stay was significantly longer in PCCL group (p<0.001).

Conclusion: Bladder stones are reasonably common clinical condition coming across in urology practice. In PCCL group though mean urethral instrumentation time was less but per urethra catheterization was longer. It is an invasive procedure with additional supra pubic catheter. Transurethral cystolithotripsy is minimally invasive procedure but urethral instrumentation is involved and hence very large stone is the limitation. Percutaneous cystolithotripsy was an effective and quick interventional method for removing large vesical calculi.
