EFFICACY OF THE EGYPTIAN PNEUMATIC LITHOTRIPTOR USING CYSTOSCOPY IN VESICAL CALCULI TREATMENT

Objective The majority of vesical calculi in adults can now be treated transurethrally with the use of different lithotriptors. The aim of this article was to study the effectiveness of the Egyptian pneumatic lithotriptor through a rigid cystoscope in the treatment of vesical calculi. Patients and Methods Fourteen adult patients (12 males and 2 females) had single urinary bladder stones. Mean stone diameter was 20 mm. Through a cystoscopic sheath, a modified ureteric catheter was introduced into the bladder. Using the Egyptian pneumatic lithotriptor KH. YG2, the pneumatic probes (rigid or flexible) were passed through the catheter for stone disintegration. Results Successful stone disintegration was recorded in 13 patients (92.9%) where the patients were stone -free at the end of the procedure. Failure of stone fragmentation occurred in one case (7.1%). The stone was removed surgically. Its chemical composition was found to be calcium oxalate monohydrate. The average time of cystolithotripsy was 35 minutes. Hospitalization ranged from 12 to 24 hours which was longer (2 to 4 days) for those patients who had undergone other procedures. Minor complications such as mild hematuria (100%) and cystitis (21.4%) were observed. No major complications were noted. Conclusion The use of the Egyptian lithotriptor during cytoscopy has been found to be an effective, easy, safe and economical method for the treatment of vesical stones.
