Methods: From March 2009 to May 2014, 36 consecutive patients with caliceal diverticular calculi were divided into 2 groups:21 patients underwent MPCNL, and 15 were treated by F-URS. All procedures were performed by one surgical group, which ensured relatively constant parameters. Patient characteristics, operative time, hospital stay after surgery, stone-free rate, symptomatic improvement rate, complications, diverticular obliteration, and stone composition were analyzed retrospectively in the 2 groups. Results: Patient preoperative variables were comparable between the two groups, with no significant difference (P>0.05). Mean operative time was 136.9 ± 22.8 min in the MPCNL group and 117.3 ± 24.3 min in the F-URS group (P ? 0.019). Hospital stay was significantly longer in the MPCNL group than in the F-URS group (9.4 ± 3.1 vs. 6.9 ± 2.1 days, P ? 0.010). The stone-free rates after MPCNL and F-URS were 90.5%(19/21) and 60.0%(9/15), respectively (P ? 0.046). Additionally, 71.4%(15/21) of patients in the MPCNL group and 46.7%(7/15) of patients in the F-URS group had symptomatic improvement at the 6-month follow-up (P ? 0.175);the rates of complications in the 2 groups were 19.0%(4/21) and 13.3%(2/15), respectively (P ? 0.650). Complete diverticular obliteration was achieved in 16 (76.2%) cases in the MPCNL group and 5 (33.3%) cases in the F-URS group (P ? 0.017). The distributions of calcium oxalate and hydroxyapatite in the stones were 66.7% (14/21) and 33.3% (7/21), respectively, in the MPCNL group;however, the distributions in the F-URS group were 46.7%(7/15) and 53.3%(8/15), respec-tively (P ? 0.310). Conclusion: MPCNL is an effective method for the treatment of caliceal diverticular calculi. However, F-URS is an alternative techniqu展开更多

Methods: From June 2012 to January 2014, a total of 52 cases of lower pole renal stones underwent retrograde intrarenal surgery (RIRS) in our center. All patients underwent a preoperative IVU and three-dimensional helical computed tomography urography (3D-CTU) program to define the collecting system anatomy, manly concerning the following lower pole features; infundibu-lopelvic angle (IPA), infundibular length (IL), and infundibular width (IW). The examinations were performed in the same cen-ter of reference with a standardized method and with 3D-HCT Siemens Somaton Plus equipment. The measurements were per-formed by the same researcher, using a ruler and a square. Results: Based on clinical threshold difference of the anatomic factors on an IVU image to compare the difference between an IVU image and a 3D-CT image of 52 patients, the IPA was<30? when measured on intravenous pyelography (IVP) for 21 patients. We found that with the IPA of<30? measured with IVP only 19%(4/21) were correctly classified in the same size category using 3D-HCT, whereas 81%(17/21) were upgraded to 40e50? on 3D-CT. This difference was significant between IVP and 3D-HCT. Conclusions: 3D-HCT has advantages over IVU when analyzing the morphometric and the morphological features of kidney lower pole spatial anatomy for the retrograde flexible ureteronephroscopy in the treatment of lower pole calyx stones.展开更多
