EFFECTIVENESS OF ESWL IN UPPER URINARY TRACT CALCULI. üst üriner sistem ta?lar?nda ESWL’nin etkinli?i.

摘要

Urolithiasis is a worldwide common medical problem. Its treatment has dramatically changed in the last decades. The best method of stone treatment is still debatable. To evaluate the effectiveness of Extracorporeal Shockwave Lithotripsy (ESWL) in treatment of upper urinary tract stones (single or multiple). A cohort study was conducted in Omdurman military hospital, Khartoum, Sudan. It included all patients with upper urinary tract stone that managed by ESWL after acceptance of the informed consent (January 2011 to April 2013). The results were evaluated after 3 months follow up. The stone-free rate was correlated with stone number, site and patient characteristics using the Student’s t test. There were 149 patients (98 males, 51 females). Their mean age was 37.9 ± 17.9 years (range 2-76 years). The locations of stone were in the kidney and ureter in 72.5% and 27.5% respectively. Response was variable in different sessions. Overall stone-free rate was 96.6%. Failure to clear the fragmented stones was in 3.4%%. Rate of complete resolution is not affected by the site of stone impaction and number of stones (p=0.8 and 0.9 respectively). ESWL is effective method in the treatment of upper urinary tract stones. ?ZET B?brek ta?lar? dünya ?ap?nda bir problemdir. Tedavisi son on y?lda dramatik bir ?ekilde de?i?mi?tir. Ancak en iyi y?ntem hala tart??mal?d?r. ESWL’nin üst üriner sistem ta?lar?n?n tedavisindeki etkinli?inin saptanmas? ama?lanm??t?r. Bu kohort ?al??ma Hartum (Sudan)’da bulunan Omdurman hastanesinde tasarlanm??t?r. Ocak 2011-Nisan 2013 aras?nda hastaneye gelen hastalar ?al??maya al?nd?. Hastalar i?lem sonras?nda 3 ay süreyle takip edildiler. Ta?s?z d?nem yüzdesi ta? say?s?, yeri ve hastan?n ?zelliklerine g?re ili?kisi Student t testi ile ara?t?r?ld?. ?al??maya 98’i erkek, 51’i bayan 149 hasta kat?ld?. Ya? ortalamas? 37.9 ± 17.9 y?ld?r (2-76). Ta?lar?n %72.5’i b?brekte, %27.5’i ise üreterde yerle?mi?ti. Tedaviye cevab?n ?e?itli fakt?rlere ba?l? olarak de?i?kenlik g?sterdi?i saptand?. Hastalar?n %96.6’s?nda ta?s?z bir d?nem sa?land?. Vakalar?n %3.4’ünde ata?lar temizlenemedi. Ta?lar?n yerle?im yeri ve say?s? tam cevapta etkili olmad??? saptand? (S?ras?yla p=0.8 ve 0.9). Sonu? olarak, ESWL’nin üst üriner sistem ta?lar?n?n tedavisinde etkili oldu?u saptanm??t?r.
