Abstract

  Purpose : To analyze clinical outcomes of transurethral lithotripsy（TUL）in patients with renal and ureteral calculi.<br>  Patients and Method : Between Jan. 2002 and Dec. 2009, we treated a total of 256 patients（13 renal stones（mean stone size : 8.2mm）, 104 proximal ureteral stones （8.3mm）, 53 middle ureteral stones（9.4mm）and 86 distal ureteral stones（7.6mm））using the pulsed dye laser. One hundred and fifty three patients（59%）had preoperative extracorporeal shock wave lithotripsy（ESWL, mean 2.6 sessions）.<br>  Results : Median operation time was 53 minutes. Proximal ureteral stone, larger size in diameter, hydronephrosis and non-expert operator were revealed as significant factors for elongation of operating time. Semirigid and flexible ureteroscope were used for 256 and 72 cases, respectively. Postoperative ureteral stents were placed in 189 cases. We experienced no severe ureteral perforation or avulsion. Only 17 patients had fevers over 38℃ postoperatively. Patients stone-free for 3 months were observed in 224 cases（89%）overall ; 11（85%）in renal, 83（81%）in proximal ureter, 48（92%）in middle ureter and 82（96%）in distal ureter. Multiple logistic regression analysis revealed that stone location（middle and distal ureter）and size（small）were independent（better）prognostic factors determining stone clearance after TUL. These success rates exceeded those of a single ESWL session which had been reported previously.<br>  Conclusion : Although TUL needs various innovative instruments, i.e. ureteroscopy or intracorporeal lithotriptor, it is relatively safe and showed higher success rate than that of ESWL in managing upper urinary tract stones.
