“…The key to the incision and drainage of parapelvic renal cysts via flexible ureteroscopy is the accurate location of the cysts. The present study suggested that the evaluation of cyst positioning should include ultrasonography, intravenous urography, retrograde pyelography, CT and an enhanced CT (2,(14)(15)(16)(17)(18)(19)(20). A recent Chinese randomized controlled trial confirmed that the injection of methylene blue into the parapelvic renal cysts reduced the identification time and operation time of the cysts under a flexible ureteroscope (21).…”

“…The surgical path of flexible ureteroscopic surgery runs closer to parapelvic renal cysts than the laparoscopic surgery anatomically (14). As this technique is transluminal naturally and leads to less bleeding, less risk and faster recovery, it has been favoured by a considerable number of urologists (2,(14)(15)(16)(17)(18)(19)(20)(21)(22). The key to the incision and drainage of parapelvic renal cysts via flexible ureteroscopy is the accurate location of the cysts.…”

“…In this study, one patient with renal cell carcinoma and four patients with simple renal cysts also underwent relevant treatment for their respective conditions during the same surgery. (4) Compared with flexible ureteroscopy, there is no need to use a double J stent before and after surgery, and this reduces the cost of treatment 21 . Patient with ureteral stricture can also undergo this surgical approach.…”

Renal cyst is a common disease in humans and laparoscopic renal cyst decortication is the gold standard for treatment. However, specialized surgical skills are required for the treatment of renal parapelvic cysts. In this study, we describe an improved laparoscopic method for the treatment of renal parapelvic cysts involving the use of continuous infusion of methylene blue. Sixteen patients with renal parapelvic cyst were enrolled in this study. All patients underwent retrograde ureteral catheterization, with continuous perfusion of the renal pelvis using a solution of 0.2% methylene blue and saline, during laparoscopic decortication of the parapelvic cyst. In one patient, the cyst communicated with the renal collection system which was injured, but this was immediately repaired intraoperatively. All operations were successful, and none was converted to open surgery. There were no occurrences of persistent urinary fistula, bleeding, or other complications postoperatively. All patients were followed-up for 3–24 months, and results of postoperative imaging investigations revealed that all of our patients experienced either complete recovery or a greater than 50% decrease in size of the cysts. Our study demonstrates that methylene blue-assisted laparoscopic treatment is a safe, effective and practical method for the treatment of renal parapelvic cysts.

Retrograde Intrarenal Surgery for Symptomatic Renal Sinus Cysts: Long-Term Results and Literature Review

et al. 2018

Introduction: To report the long-term multicenter experience with retrograde intrarenal holmium-laser incision (RIR-HoLI) in the management of symptomatic renal sinus cysts (RSCs). In the literature, RIR-HoLI has been shown to be a safe and effective treatment, but there are only a few reports regarding long-term results and reproducibility of this procedure. Material and Methods: From June 2010 to June 2015, 14 patients with symptomatic RSCs underwent RIR-HoLI. The mean age was 52.1 ± 11.28 years (range 28–77) and the mean cyst size was 53.2 ± 14.23 mm (range 35–90). In all cases, contrast-enhanced computer tomography (CT) showed compression of the renal pelvis by the cyst (no malignancy). Surgical outcome was assessed in terms of symptoms improvement (measured by Visual Analogue Scale [VAS] for pain) and renal ultrasound findings at 3–6–12 months postoperatively and then yearly. CT scan was carried out at 12 months follow-up. Results: RIR-HoLI was successful in all patients. The mean operative time was 47.8 ± 13.54 min (range 30–80) and mean hospital stay was 3.5 days (range 2–5). There were 2 Clavien grade II complications (flank pain and urgency delaying discharge). After surgery, all patients became asymptomatic (VAS score change, p = 0.0001). One patient had persistence of a small cyst (10 mm). Mean follow-up is 44 ± 17.24 months (range 24–84); all patients remained asymptomatic, with no signs of recurrence. Conclusions: RIR-HoLI proved to be a safe and effective treatment for symptomatic RSCs. In our experience, it provided excellent long-term results and was reproducible at 4 different institutions.
