“…[8] So far, some studies have investigated stone opacity effect on ESWL outcomes. [12,13] Also, some other studies have studied the relationship between stone density and ESWL or PCNL outcomes. [14][15][16][17] To our knowledge, no study has compared the results of PCNL in patients with radiopaque and radiolucent stones.…”

Objective: This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. Material and methods:The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis.Results: There were no significant differences in age, sex, body mass index, hypertension, diabetes mellitus, pre-surgery hemoglobin, pre-surgery serum creatinine, stone and also surgery-related parameters between the two groups. Stone free rate, surgery time, complication-related parameters, hemoglobin drop, serum creatinine and glomerular filtration rate (GFR) changes were similar in both groups based on univariate analysis. The radiopaque group had higher post-surgery GFR (p= 0.04) and longer hospital stay (p= 0.009). However, opacity had no effect on these outcomes after multivariate analysis. Higher post-surgery GFR was seen in patient with higher GFR before surgery (p<0.0001). Also, higher hemoglobin before surgery was correlated with less hospital stay (p= 0.001). Conclusion:The complete supine percutaneous nephrolithotomy outcomes are similar in patients with radiopaque and radiolucent stones.

“…We found that patients with radiopaque stones had significantly higher treatment failure rates (OR, 2.351; 95% CI, 1.049–5.267). The efficacy of ESWL for treating radiolucent ureteral calculi localized by intra-operative IVU has been studied, with reported outcomes comparable to those of radiopaque ureter calculi [ 6 ]. Previous studies demonstrated that radiolucency, defined by using plain radiography, may also present with a lower stone attenuation value on non-contrast CT [ 30 ].…”

“…With a sensitivity of 94–100% and specificity of 92–100%, NCCT is more effective than IVU as a first-line confirmation tool for ureteral stones in the emergency department[ 1 ]. However, IVU is more convenient than NCCT as an intra-operative adjunct for radiolucent ureteral stones if ultrasonic localization is not possible[ 6 ]. NCCT may be less accurate in localizing the suspected calculi due to impaired resolution of soft tissue structures [ 7 ].Radiation exposure is also around 1.5 times higher for NCCT than for IVU [ 8 ].…”

ObjectivesNon-contrast computed tomography (NCCT) is not always performed clinically if the diagnosis of ureteral calculi has been confirmed using other radiographic imaging modalities. The aim of this study was to identify predictors of successful extracorporeal shockwave lithotripsy (ESWL) without assistance of NCCT.MethodsWe retrospectively reviewed the medical records of patients with symptomatic solitary ureteral stones who underwent ESWL between November 2015 and January 2016. Abdominal plain radiography or intravenous urography were performed before ESWL for localization. The exclusion criteria were repeated sessions of ESWL for the target stone and congenital genitourinary tract anomalies. The demographic characteristics, clinical history, medical charges, or imaging features of the stones were recorded. Successful treatment was defined as no fragments detected on radiography or ultrasonography in 4 weeks. For radiolucent calculi, successful treatment was regarded as cases without hydronephrosis, symptoms, or hematuria. Patients experiencing intractable pain and undergoing subsequent auxiliary surgeries were regarded as having ESWL treatment failure.ResultsAge (odds ratio [OR], 1.042; 95% confidence interval [CI], 1.007–1.078), history of ipsilateral renal or ureteral calculi episodes (OR, 2.669; 95% CI, 1.281–5.687), stone burden (OR, 3.499; 95% CI, 1.284–9.530), and radiopaque stone (OR, 2.351; 95% CI, 1.049–5.267) were significant predictors of ESWL failure in all patients.ConclusionsFor treating symptomatic ureteral stones, those with smaller size, radiolucency, and without a history of ipsilateral renal or ureteral calculi could be considered for first-line therapy with ESWL.

“…ESWL tedavisinde bir diğer sorunlu grup da opak olmayan taşlardır. ESWL tedavisi intravenöz kontrast madde verilerek taşın üreterdeki yerinin tespiti ile mümkün olmaktadır (9). Ancak biz bu özelikteki hastalarda ESWL yerine üreteroskopik girişimi tercih ettik.…”

ÖZETAmaç: Üreter taşlarının tedavisinde rijit üreteroskopi (URS) ve vücut dışı şok dalgalarıyla taş kırma (ESWL) tedavisinin sonuçları, taşın üreterdeki konumu ve taş boyutuna göre değerlendirildi. Gereç ve Yöntem:Çalışmada üreter taşı tanısı olan rijit üreteroskopi ile pnömotik litotripsi tedavisi uygulanan 79 hasta ve ESWL uygulanan 185 hasta değerlendirildi. Taşlar üreterdeki yerine göre alt, orta ve üst üreter olarak 3 gruba, taşın boyutuna göre <10 mm ve >10 mm olarak 2 gruba ayrıldı. Başarı oranları ve ek tedavi gereksinimleri değerlendirildi. Bulgular:Ortalama taş boyutu üreteroskopi grubunda 10.3 mm (7_18), ESWL grubunda 9.7 mm (6-17) olarak saptandı. Taşın üreterdeki yerine göre başarı oranı üreteroskopi grubunda üst, orta ve alt üreter için sırası ile %55.5(5/9), %92.8 (26/28), %97.6 (41/42) olarak saptandı. ESWL grubunda ise bu oranlar sırası ile %87.5 (113/129), %76.9 (40/52), %50.0 (2/4) olarak saptandı. Üreteroskopi grubunda <10 mm ve >10 mm üreter taşlarında başarı oranları sırası ile %94.2 (33/35), %88.6 (39/44) olarak saptandı (p<0.05). ESWL grubunda ise bu oranlar sırası ile %88.6(86/97), %78.4 (69/87) olarak saptandı (p<0.05). Taşın yeri ve boyutundan bağımsız olarak genel başarı oranı üreteroskopi grubunda %91.1 (72/79), ESWL grubunda %83.7b(155/185) olarak saptandı (p<0.05). Sonuç:Her ne kadar üreteroskopi grubundaki genel başarı oranımız ESWL grubundakinden daha yüksek olsa da üst üreter taşlarındaki üreteroskopi başarı oranımız ESWL grubuna göre düşüktür.Anahtar Sözcükler: Ekstrakorporeal şok dalga litotripsi (ESWL), Üreter taşı, Üreteroskopi (URS). SUMMARYAim: Rigid ureteroscopy and extracorporeal shock wave lithotripsy treatment results were evaluated according to the size and localization of the stones in the treatment of ureteral stones.
