Background: To assess the validity and feasibility of the modified hand-assisted retroperitoneoscopic laparoscopic nephrectomy (MHARLN) in patients with benign inflammatory non-functioning kidney diseases. Methods:We retrospectively compared the data of 223 patients who underwent an MHARLN (n=142) or an open nephrectomy (ON) (n=81) with benign inflammatory non-functioning diseases between January 2014 and October 2019 at our hospital. Patients' demographic data, perioperative outcomes, preoperative and postoperative inflammatory data, and postoperative complications were reviewed. Results:The basic demographic data of patients were similar between the 2 groups. The mean operative times for the MHARLN and the ON were 135 and 143 minutes (P=0.181), respectively. The first time at which postoperative ambulation occurred, the visual analog pain scale (VAS) score before discharge and the postoperative complication rate were similar in both groups. However, compared to the MHARLN, the ON was associated with a more severe inflammatory response on the first day after surgery (P=0.045), higher estimated blood loss (309.8 vs. 139.6 mL; P=0.036), more peritoneal ruptures (19.8% vs. 9.2%; P=0.024), higher intraoperative transfusion (14.82% vs. 4.93%; P=0.011), higher VAS scores 24 hours after surgery (5.9 vs. 5.2; P=0.002), additional analgesic use (35.8% vs. 21.8%; P=0.024), and longer hospital stays (5.3 vs. 4.6 days; P=0.048). Before a liquid diet was commenced in the MHARLN and ON groups, the mean time was 1.2 and 1.5 days, respectively (P=0.004).Conclusions: When performed by a skilled laparoscopic surgeon, the use of the MHARLN in patients with benign inflammatory non-functioning kidney diseases is reliable and safe. The MHARLN may help to treat challenging cases and result in less trauma successfully.

BackgroundThe purpose of this study was to report our experience in treating multiple ureteral polyps with transabdominal laparoscopic ureteroureterostomy (LAP-UU) with intraoperative retrograde ureteroscopy (RU)-assisted technique.MethodsThe data of 32 patients who underwent transabdominal LAP-UU with the intraoperative RU-assisted technique due to multiple ureteral polyps between January 2011 and March 2021 were reviewed at our institute. After administration of anesthesia, patients were placed in a passive position and underwent a three-port transabdominal laparoscopy with RU. Detailed data were reviewed, such as demographic characteristics, intraoperative outcomes, postoperative data, complications, and pathology reports.ResultsThirty-two patients were diagnosed with multiple ureteral polyps underwent this surgery method at our institution. The mean duration of symptoms at the time of diagnosis was approximately 7.1 months. The mean age of patients was 42.4 years, with men accounting for 68.8% (22/32), lesion of left for 56.3% (18/32), and the upper ureter for 62.5% (20/32). Furthermore, the median length of the polyps was 3.6 cm, the mean operative time was 174.6 min, and the estimated blood loss (EBL) was about 86.8 ml. The mean time to begin a liquid diet and to be out of bed were 1.7 and 2.3 days, respectively. The average length of hospital stay was 6.3 days. The ureteral stent was removed by cystoscope 2–3 months after surgery. Follow-up duration ranged from 3 to 112 months and none of the patients required another surgery for recurrence.ConclusionTransabdominal LAP-UU combined with the intraoperative RU-assisted technique is an effective, safe, and reliable surgical option for patients with multiple ureteral polyps. Further long-term follow-up is recommended.
