“…Comparing the results reported in relation to the dusting technique and conventional basketing retrieval technique, our present operation time and SFR were comparable with the previous reports [ 10 , 13 , 14 ] in Table 3 . The one-surgeon basketing technique tends to be difficult to perform but, with the right instruction, can be conducted adequately by a new operator within the span of just a few cases [ 11 ]. Therefore, the one-surgeon basketing technique is not extremely difficult to learn.…”

“…Further, depending on the case, basketing retrieval is considered a necessary approach. However, there are few reports available regarding the use of the one-surgeon basketing technique [ 10 , 11 ]. In most cases, the two-person conventional extraction method has been used at the time of extraction during f-URS; therefore, the presence of a surgeon and an assistant is necessary during the surgery.…”

Objective : To evaluate the safety and efficacy of using one-surgeon basketing technique by a solo surgeon for stone extraction during flexible ureteroscopy (f-URS) for urolithiasis. Patients and methods : This retrospective study enrolled patients with urinary calculus who underwent f-URS at two institutions in Japan between September 2014 and March 2020. A total of 100 patients were operated by one experienced surgeon using the one-surgeon basketing technique. With this approach, the f-URS apparatus was manipulated with the non-dominant hand and the basket catheter was manipulated with the dominant hand. We retrospectively examined the perioperative results, complications, and stone-free rate [with ‘stone free’ defined as ≤2 mm with kidney–ureter–bladder (KUB) at 1 month after f-URS] to estimate the safety and efficacy for comparison with the results of conventional retrieval basketing technique. Results : Among our study population, the median stone size was 14 mm and median operative time was 74 min. A stone-free status was achieved in 91 patients (91%). The median stone fragmentation time was 15 min and stone retrieval time was 30 min. All included patients were treated using the one-surgeon basketing technique. Complications related to stone retrieval were identified in two patients (2%); the degree of ureteral injury was classified as Clavien–Dindo Grade IIIa. Conclusion : The one-surgeon basketing technique is safe and effective for the extraction of stone fragments during f-URS for urolithiasis. This technique does not require assistance for basketing; therefore, f-URS with active retrieval basketing can be completed by a solo surgeon.

“…Elsewhere, Anan et al compared the surgical outcomes of the onesurgeon basketing technique between a well-trained surgeon group and a less-trained surgeon group; there was no significant difference between them. 4 In their most recent study, Okada et al suggest, however, that the surgical outcomes, including stone-free rate and operative time, could be improved by off-site training or surgical experience. 3 Second, the number of times the basket forceps were opened and closed during stone catching was significantly lower by the one-surgeon basketing technique than by the two-surgeon technique.…”

“…Furthermore, the recurrence rate of urolithiasis has been reported to be as high as 50% at 5 years and 80-90% at 10 years (3,4). Due to technological advances, such as ureteral access sheath, holmium laser, and stone basket, which enable the management of intrarenal stones, flexible ureteroscopy (f-URS) has been established as a minimally invasive modality to treat intrarenal calculi (5)(6)(7). Impacted ureteral stones are defined as those that remain in one position for >2 months (8).…”

Background: The treatment of impacted upper ureteral stones with hydronephrosis remains a challenge for urologists. The current study aimed to evaluate the impact of preoperative percutaneous nephrostomy (PNS) as a treatment strategy before flexible ureteroscopy (f-URS) of asymptomatic impacted upper ureteral stones with hydronephrosis.Methods: This multicenter retrospective study included patients who underwent PNS (group A, n=61) and those who did not (group B, n=75) before f-URS for asymptomatic impacted upper ureteral stones with hydronephrosis. Impacted ureteral stones are defined as those that remain in one position for >2 months.Operative outcomes, including stone-free rate, operation time, postoperative hospital days, and complication rate, were evaluated.Results: There were no significant differences in age, sex, and stone size between the two groups except in the grade of hydronephrosis, with group A having more cases of advanced hydronephrosis than group B. The stone-free rate was significantly higher in group A than in group B [95% vs. 77% (P=0.004)]. However, there were no significant differences between the groups in operation time [55 vs. 55 min (P=0.84)], postoperative fever [5% vs. 5% (P=1.00)], and postoperative hospital days [2 vs. 2 days (P=0.44)]. In group A, preoperative PNS placement was performed 4 days before f-URS, and the PNS was removed postoperatively on the same day of the f-URS. Additionally, subgroup analysis was performed in cases of grade 2 and 3 hydronephrosis. A total of 110 patients, 60 who underwent f-URS with PNS and 50 who underwent f-URS without PNS, were included. The stone-free rate was significantly higher in f-URS with PNS than in f-URS without PNS [95% vs. 76% (P=0.005)]. However, no significant differences were found between the groups in operation time, ureteral injury, postoperative fever, and postoperative hospital days.Conclusions: At grade 2 or 3 hydronephrosis, preoperative PNS as a treatment strategy for a few days prior to f-URS for impacted upper ureteral stones improved the stone-free rate without increasing the operation time and postoperative length of hospital stay.
