Fluoroscopic Time

Introduction: Fluoroscopic guidance is routine for endourological procedures like percutaneous nephrolithotomy and retrograde intrarenal surgery in vast majority of centers. It is used for the initial retrograde ureteral access to define the pelvicalyceal system, puncture of the desired calyx and dilatation of the tract, aid navigation of stones and calyces, and placement of guide wires and stents. Both the patient and operating staffs are exposed to the radiation during surgery. The purpose of this study is to measure that exposed fluoroscopic radiation dose during these procedures and make operating surgeons aware of their fluoroscopic habit. Materials and Methods: This is prospective observational study, who underwent percutaneous nephrolithotomy (n=60) and retrograde intrarenal surgery (n=43) in our institute between December 2017 and August 2018. Percutaneous nephrolithotomy was done in prone position with prior insertion of ureteric catheter. Retrograde intrarenal surgery was carried out with or without insertion of ureteral access sheath. Fluoroscopic time was taken from the insertion of the ureteric catheter or UAS to the completion of the procedure with double J stenting. Results: For percutaneous nephrolithotomy and retrograde intrarenal surgery group, mean stone size were 21.89 mm and 10.56 mm; mean fluoroscopic time were 117.95 s (range 24-350) and 31.83 s (range 3-103); mean fluoroscopic dose were 29.71 mGy and 6.19 mGy respectively.

Conclusions: Among the endourological procedures for renal stones, retrograde intrarenal surgery was associated with less fluoroscopic hazard than percutaneous nephrolithotomy. Awareness of fluoroscopic exposure duration and experience of a surgeon can minimize the radiation hazard during endourological procedures.

Abstract Background The goal for using smaller caliber instruments in PNL was to reduce the access-related complications and to decrease morbidity. The objective of this study was to evaluate the safety and efficacy of Chinese minimally invasive percutaneous nephrolithotomy (MIPNL) in the treatment of renal stones ≤ 20 mm. Results Sixty-seven patients completed the study protocol. The mean age was 41.10 ± 13.99 years (range 18–68 years). There were 43 (64%) male and 24 (36%) females. The mean stone size was ranged from 78.5 to 439.6 mm2 (mean ± SD 172.48 ± 69.54 mm2). The overall SFR was (82%). Twelve (18%) needed post-MIPNL auxiliary procedure, in the form of second MIPNL in 3 (4.5%) cases, SWL in 7 (10%), and RIRS in 2 (3%) cases. The intraoperative complication was present in four patients (5%) include bleeding necessitate blood transfusion in one patient (1.5%) and renal collecting system perforation 3 (4.5%). The postoperative complication was urine leakage 5 (7.5) and fever in 6 (9%) of patients. Conclusion Chinese MIPNL is safe and effective method for treatment of renal stone ≤ 20 mm size with satisfactory SFR and low complication rate when SWL failed or contraindicated. It is considered a feasible treatment alternative to standard PNL, in the absence of flexible URS or miniature nephroscope.

Detailed Clinical Information

This study was to evaluate the risk factors of infectious complications after percutaneous nephrolithotomy (PCNL) and build a prediction tool for postoperative complications based on the risk factors. A total of 110 male (67.1%) and 54 female (32.9%) patients who underwent PCNL for renal stones between 2010 and 2014 in our institute were included. A detailed clinical information and laboratory results were obtained from patients. Systemic inflammatory response syndrome (SIRS) and postoperative fever were recorded after PCNL surgery. In all, 45 cases (27.4%) developed SIRS and fever was observed in 20 cases (12.2%). In multivariate analysis, stone size (odds ratio, OR = 1.471,p=0.009) and urine white blood cell (WBC) (OR = 1.001,p=0.007) were related to the development of SIRS. Stone size (OR = 1.644,p=0.024), urine WBC (OR = 1.001,p=0.002) and serum albumin (OR = 0.807,p=0.021) were associated with postoperative fever. We concluded that patients with larger stone size and preoperative urinary tract infection might have a higher risk of developing SIRS and fever after operation, while a high-normal level of serum albumin might be the protective factor for postoperative fever.

Background: Advancements in the endoscopic armamentarium, retrograde intrarenal surgery has become a viable and attractive option for the treatment of renal stones because of its high stone-free rates (SFRs) and low morbidity. Objective: To describe our experience and outcome of RIRS for the treatment of renal stones and to assess its effectiveness and safety. Design, setting, and participants: A retrospective analysis of 60 patients who underwent RIRS for renal stones at our institute between January 2018 to December 2018 was performed. Surgical procedure: Flexible ureteroscopy and laser lithotripsy using a standardized technique with last-generation flexible ureteroscopes (Flex-Xc) using Holmium-YAG laser. Outcome measurements and statistical analysis: Clinical data were collected and intraoperative and postoperative outcomes were assessed (Ureteral access sheath placement, operation time, hospital stay, stone free rate, post-operative blood transfusion & fever, need for second session of RIRS. A descriptive statistical analysis was performed. Results and limitations: The mean overall stone size was 13±3 mm. Pre stenting done in all cases. Ureteral access sheath placement was possible in 54(90%) patients. At 1 month follow-up, the overall primary SFR was 86.67%(52 cases), the secondary SFR was 96.67%(58 cases).The mean operative time was 91.96±18.7 min. Mean hospital stay was 1.86±1.02 days. Complications were reported in 8 (13.33%) patients overall, with fever in 6 patients (10%), steinstrasse in 2(3.33%) patients need for second session RIRS in 6 patients (10%).No patient needed blood transfusion. The main limitation of the study is the retrospective nature. Conclusions: RIRS performed using a flexible ureterorenoscope marked the beginning of a new era in urology. It is safe and effective procedure and an alternative to extracorporeal shock wave lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL) in the treatment of selected renal stones.
