Changes in the management of urolithiasis : endourologic treatment of calculi in the upper urinary tract
Three hundred seventy cases with calculi in upper urinary tract were treated by endourology, 210 cases were subjects of percutaneous nephrolithotripsy (PNL) and 160 cases of transurethral ureterolithotripsy (TUL), in Nara Medical University Hospital and 13 affiliated hospitals. Of the PNL cases, PNL...

| Zusammenfassung: | Three hundred seventy cases with calculi in upper urinary tract were treated by endourology, 210 cases were subjects of percutaneous nephrolithotripsy (PNL) and 160 cases of transurethral ureterolithotripsy (TUL), in Nara Medical University Hospital and 13 affiliated hospitals. Of the PNL cases, PNL was completed in 184 cases (87.6%) and not completed in 16 cases (12.4%). 168 cases (80.0%) had successful results by PNL alone, stone-free or stone fragments less than 5 mm, in spite of the stone location and size. No serious adverse effect was experienced throughout the study. However, changes like a scar formation or fibrosis around the nephrostomy tract were revealed as a late complication by excretory urography, computed tomography and renal scanning. Of the 160 TUL cases, TUL was successful in 132 cases (82.5%) and unsuccessful in 28 cases (17.5%). The results of TUL for the calculi above the upper iliac cresta were not favorable, success rate for stone 6-10 mm in diameter was 70.3% and that for stones larger than 11 mm 37.5%. However, the results of TUL for the calculi below the upper ileac cresta were favorable, the success rate for the 6-10 mm calculi was 91.5% and for the calculi larger than 11 mm 88.4%. Of 28 TUL failures, 7 cases underwent PNL and 21 cases received open surgery. Throughout our endourologic treatments, the most problematic stone was calculi impact in the ureter. The indication of endourology for the calculi in upper urinary tract is discussed with consideration of ESWL which is becoming the main stream of stone treatment |
