“…The stone-free rate of tf-URS group was lower than that previously reported [ 4 ], which may be associated with the selection of calculi location and the degree of intraoperative stone crushing. No residual calculi or calculi diameter ≤ 2 mm based on CT examination without clinical symptoms should be defined as stone-free status [ 11 ]. The stone-free rates at 3 months after surgery of tf-URS and FURS groups were lower than that of SMP group, but there was no significant difference.…”

“…Operation time referred to a period from the time when the scope was inserted into the body to the time when the scope was removed from the body. For the definitions on stone-free status, different studies [ 10 , 11 ] has some differences on the size of stone fragments. In this study, stone-free status referred to the scope smoothly reaching target calices and pulverizing calculi into small fragments less than 2 mm [ 11 ].…”

Background This retrospective study was conducted to compare the safety and efficacy of Sun’s tip-flexible semirigid ureterorenoscopy (tf-URS), super-mini percutaneous nephrolithotomy (SMP) and flexible ureteroscopy (FURS) in treating upper urinary tract calculi, including upper ureteral or renal calculi. Methods We included patients with upper ureteral calculi or renal calculi 1.0–2.0 cm in size, who underwent tf-URS, SMP or FURS, respectively. The indicators reflecting safety and efficacy were compared among the three surgical techniques. Results SMP presented with higher single stone crushing success rate, but longer operation time and postoperative hospital stay, more blood loss, and higher postoperative pain score compared with FURS and tf-URS (P < 0.05). The hospitalization cost of tf-URS group was lower than that of SMP and FURS groups (P < 0.05). The incidence of postoperative fever in tf-URS group was significantly higher than that in SMP group (P < 0.05). No significant difference was found in mucosal injury, perirenal hematoma, and stone-free rate at 3 months after surgery (P > 0.05). Conclusions tf-URS and FURS have the advantages in minimal invasion, hospitalization cost, patient comfort, and hospital stay while SMP has higher stone-free rate. These three surgical techniques are safe, reliable and complementary, which should be selected according to the actual situation.

“…The surgeries were mainly performed by three experienced surgeons at our institutions. All patients underwent a standard surgical procedure (Figures 1,2) (12). In group A, a PNS (8 or 10 Fr) was inserted by urologists, under local anesthesia and fluoroscopy, after the patients' admission to the hospital and retained for a median of 4 days (range: 2-6 days) before f-URS (Figure 1B).…”

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.

“…The e cacy of the one-surgeon basketing technique has been demonstrated [8,9]. In this method, the surgeon handles the exible ureteroscope with one hand and simultaneously manipulates the basket forceps with the other hand, as opposed to the conventional two-surgeon basketing technique in which two surgeons separately handle the exible ureteroscope and basket forceps.…”

When performing flexible ureteroscopic lithotripsy for upper urinary stones, an important treatment option is stone extraction. In this study, we aim to investigate the surgical factors affecting the efficiency of stone extraction and surgeon stress using a flexible ureteroscopic lithotripsy simulator model. This simulator-based study involved 16 participants: eight urologists and eight residents. Participants each performed two tasks eight times, with two types of ureteral access sheath (Flexor or Navigator), with or without M-arm, and with left or right kidney models. Task1 was to touch each renal calix with the ureteroscope, and Task2 was to extract stones. The recorded outcomes of this study were the number of times that the ureteroscope got stuck during insertion, the number of times a stone was dropped during removal, the number of times the basket forceps were opened and closed, and the time required to accomplish each task. The number of times that the ureteroscope got stuck was significantly higher when Navigator was used compared with Flexor overall, and for urologists and residents (all P < 0.01). The number of times a stone was dropped was significantly higher in the ipsilateral group than in the contralateral group overall (P = 0.01), and the number of times the basket forceps were opened and closed was significantly higher in the ipsilateral group than in the contralateral group both overall and for residents (all P < 0.01). Differences in ureteral access sheath and the kidney side were surgical factors affecting the efficiency of stone extraction during flexible ureteroscopic lithotripsy with the one-surgeon basketing technique.
