“…Gdor et al (14) reported a success rate of endoscopic treatment of upper ureteral calculi of only 56%. The minimally invasive nephroscope treatment had a higher efficiency for upper ureteral calculi, with a success rate of 90.9% (5). However, injury to kidney tissue resulted in larger trauma and even serious injury, including bleeding, hemopneumothorax, hematosepsis and tissue injury.…”

“…Due to the stone obstructing the ureteral cavity, drainage of the fluids used for flushing is hindered and a larger pressure is required for the process, which has the potential of moving the stone into the wrong direction (3,4). PCN suggested better curative effects with 90.09% success rate of lithotripsy (5), but causes a larger surgical wound and bears risks of hemorrhoea, hemopneumothorax, sepsis and peripheral tissue injury during or following surgery. Soft ureteroscopy treatment has improved safety and effects to the upper ureteral calculi, but requires highly trained surgeons to treat ureteral incarcerated stones.…”

The present study assessed the clinical efficacy of guide sheath-assisted ureteroscope lithotripsy in the treatment of upper ureteral calculi. A total of 81 patients with upper ureteral calculi underwent ureteroscope lithotripsy assisted by a guide sheath between January 2012 and June 2014; of these, 63 patients were successfully treated with simple rigid ureteroscope lithotripsy assisted by a ureteral access sheath, and 18 patients were successfully treated with rigid and flexible ureteroscope lithotripsy assisted by a guide sheath. At 1 day after the surgery, ultrasound examination of kidneys, ureters and bladder, and urinary system computed tomography were used to re-check for residual stones, and 69 patients had stones with a diameter of <2 mm in the renal pelvis, while 12 had stones of 2–4 mm in diameter. The operation time was 30–115 min (average, 56.0±4.8 min); all patients underwent a successful surgical procedure. A total of 7 patients had an elevated temperature 37.4–39.1°C (mean temperature, 37.7±0.3°C) after the surgery, but no other major complications were noted. After 1 month, the residual stones were completely discharged, so that the stone clearance rate was 100%. All patients were followed up for 3–12 months and no associated complications occurred. Overall, ureteroscope lithotripsy assisted by a guide sheath for the treatment of upper ureteral calculi had the benefit of water injection and reflux functions, as well as enhanced vision, reduced pressure within the renal pelvis, good discharge of stones as well as an improved efficiency and success rate compared with simple ureteroscopic lithotripsy.

“…[1] Ureteroscopy (URS) is the standard treatment for ureteral stones together with shock wave lithotripsy (SWL) and antegrade percutaneous nephrolithotomy in patients with indications for active stone removal or following failed conservative management. [2][3][4] Technical improvements especially in the last decade provided better optical quality and miniaturization of the instruments leading to worldwide increase in application of URS for the management of ureteral stones. Recently published results of The Clinical Research Office of the Endourological Society (CROES) URS Global Study revealed satisfactory success rates (85.6% stone-free rate) with lower complication rates (3.5% in all).…”

Objective: Hydronephrosis developing following ureteroscopy (URS) is an important issue associated with the long-term postoperative renal functions. Studies investigating the role of postoperative imaging revealed conflicting results. In this study, we aimed to determine the incidence and predictors of hydronephrosis following semirigid URS. Material and methods:We evaluated the results of 455 patients who underwent URS and postoperative imaging with non-contrast computed tomography (CT). Primary endpoints of the study were to determine the frequency of development of hydronephrosis and factors associated with the development of hydronephrosis. Logistic regression analysis was used to define factors effecting on the development of hydronephrosis.Results: Postoperative non-contrast CT revealed hydronephrosis in 81 (17.8%) patients. Stone-free status was achieved in 415 (91.2%) patients. Univariate analysis revealed history of ipsilateral URS (p= 0.001), duration of operation (p=0.022), presence of multiple stones (p=0.001), and occurrence of a renal colic episode postoperatively (p=0.013) as the parameters associated with increased risk of postoperative hydronephrosis. In the multivariate analysis, history of ipsilateral URS (OR: 2.724, p=0.017) and presence of multiple stones (OR: 2.116, p=0.032) were found to be the independent prognostic markers of developing postoperative hydronephrosis. Conclusion:Ipsilateral hydronephrosis following URS develops in a significant number of patients. In patients with history of ipsilateral hydronephrosis and multiple stones, risk of development of postoperative hydronephrosis is higher, therefore physicians should be keep these parameters in mind in the decision making process of selective imaging postoperatively.
