“…In two of our cases, the percutaneous puncture shaft was removed immediately without nephrostomy tube placement. The mean hospital stay was only 1.2 days, which is significantly shorter than the 4 days with PCN ( 8 ) or the 3.2 days with laparoscopy ( 20 ) reported in previous studies. This shorter convalescence can be attributed to the reduced invasiveness of our procedure.…”

“…To date, there are only a few published studies describing treatments for parapelvic cysts with concomitant calculi. Chen et al ( 8 ) reported the effectiveness of percutaneous intrarenal cyst marsupialization and simultaneous nephrolithotomy in the management of renal cysts with ipsilateral calculi in 16 patients, of which only two cases involved parapelvic cysts. In their study, the optimal puncture route was selected to marsupialize the cyst and approach the target calyx.…”

Objective:To assess the safety, feasibility, and efficacy of simultaneous treatment of parapelvic renal cysts and stones by flexible ureterorenoscopy with a novel four-step cyst localization strategy in selected patients.Patients and Methods:We retrospectively reviewed 11 consecutive cases of parapelvic renal cysts with concomitant calculi treated by flexible ureterorenoscopy and laser lithotripsy (FURSL). Marsupialization was performed subsequently with holmium: YAG laser in our institution. Fragmentation was used to manage renal stones and a novel four-step cyst localization strategy was applied in each case for marsupialization.Results:There were no intraoperative complications. Two cases of cystitis were reported postoperatively. The mean operative times of FURSL and marsupialization were 23.6 ± 3.9 minutes and 29.1 ± 9.7 minutes, respectively. During marsupialization, seven patients underwent the first two steps of the new strategy, two patients underwent three steps and two patients underwent all four steps. The mean reduction in hemoglobin level was 4.7 ± 1.7 g / L (range 3-8 g / L). The mean length of hospital stay was 1.2 ± 0.4 days. During a mean follow-up duration of 18 months, all cases remained stone-free and there was no stone recurrence. Parapelvic cysts became undetectable in eight cases and decreased in size by at least half in three cases.Conclusion:With appropriate patient selection, FURSL and marsupialization with a four-step cyst localization strategy is feasible, safe, and effective in treating parapelvic renal cysts with concomitant calculi.

“…In our study, 5 renal cyst patients with coexisting ipsilateral calculi showed a good therapeutic effect, which could decrease the costs and the risks associated with a potential second operation. This viewpoint is further supported by a recent study by Chen et al ., who described percutaneous intrarenal marsupialization and concomitant nephrolithotomy for the treatment patients with a renal cyst and ipsilateral calculi and follow-up results have confirmed the safety and efficacy of the procedure 22 .

Most simple renal cysts rarely require therapy. When it grows to such a large size, regardless of the presence of symptomatology, surgical intervention is required. In this study, we explored a new approach called percutaneous ureteroscopy laser unroofing for treatment renal cysts and evaluated its safety and efficacy. 71 simple renal cyst patients with surgical indications were enrolled, including 6 patients with a peripelvic cyst and 5 patients coexisting ipsilateral calculi. Under ultrasound guidance, an eighteen-gauge needle was placed inside the cyst cavity, and a guidewire was introduced followed by sequential dilation up to 28 F. The extra-parenchymal portion of cyst wall was dissociated and incised using either a Thulium or Holmium laser, and a pathological examination was performed. Renal calculi were treated simultaneously. For peripelvic cyst patients, one end of a double-J stent was inserted into the cyst cavity to prevent auto-closure. Mean of 11.7 months follow-up, the results showed that the cyst was completely resolved in 53 patients, its size was reduced to less than 50% in 15 patients, and treatment failed in only 3 anterior cyst patients, suggesting that percutaneous ureteroscopy laser unroofing is an effective and less invasive alternative for treatment of renal cysts in selected patients.

“…The cyst can be in the way of the puncturing axis and, in some cases, may need to be aspirated before completing the puncture [3,20]. Chen and coworkers [21] performed trans-cystic PCNL with intrarenal cyst marsupialization on 16 non-ADPKD patients without serious complications in a mean follow-up of 21 months. They found it was a safe and effective technique.…”

Fluoroscopy versus ultrasonography guided mini-percutaneous nephrolithotomy in patients with autosomal dominant polycystic kidney disease

The objective of the study was to compare the therapeutic outcomes between the ultrasonography-guided (USG) and the fluoroscopy-guided (FG) mini-percutaneous nephrolithotomy (MPCNL) for the treatment of large or complex upper urinary tract stones (S.T.O.N.E. scores 5-11) in patients with autosomal dominant polycystic kidney disease (ADPKD). 45 ADPKD patients who were suffering from large or complex upper urinary tract stones (S.T.O.N.E. scores 5-11, mean score 7.6) in 45 renal units were accrued into this retrospective study. They were treated by either USG (20 patients) or FG (25 patients) MPCNL in our center. The treatment results as well as the complications according to the modified Clavien system were assessed and compared. The FG MPCNL group had a higher success rate in accessing the targeted calyces than the USG MPCNL group (96 vs. 70 %, p = 0.048). There was no significant difference observed between the two groups with respect to the operative time, the mean hemoglobin drop, and the stone free rate. The overall operative complications and the perioperative blood transfusion rates were significantly higher in the USG than the FG MPCNL groups, 71.4 vs. 29.2 %, p = 0.011, and 35.7 vs. 4.2 %, p = 0.018, respectively. There was no significant difference between these two groups in terms of major complications (Clavien score 3a-4a) (p = 0.542). In our center, the FG MPCNL was a superior modality to the USG MPCNL in the treatment of large or complex kidney stones in the ADPKD patients. It resulted in higher successful calyceal punctures and less operative complications.
