OBJECTIVETo evaluate the feasibility of retroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis for treatment of renal and ureteral calculi.

METHODSIn February 2010, 2 patients with renal and ureteral calculi underwent retroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis.

RESULTSThe operation time in these two cases was 70 and 80 min, and the volume of intraoperative blood loss was about 20 ml. The exposure was excellent, and the patient recovered rapidly without complications or residual calculi.

CONCLUSIONRetroperitoneal laparoscopic surgery combined with ureteroscopic lithotomy through the pelvis is feasible for treatment of renal and ureteral calculi.

OBJECTIVETo discuss the clinical characteristics of primary hyperparathyroidism (PHPT) with kidney stones.

METHODSThe clinical data of 23 cases undergoing diagnostic evaluation and surgery for PHPT combined with kidney stones between January 2004 and February 2012 was retrospectively analyzed. The 23 cases had undergone preoperative parathyroid neck color ultrasound, CT or (99)mTc-methoxy isobutyl isonitrile ((99)mTc-MIBI) diagnosis. The surgical treatment included parathyroid disease and kidney stones. The intravenous calcium, phosphorus and serum intact parathyroid hormone (iPTH) levels, 24 hours urinary calcium concentrations were measured 3 days before and 7 days after surgery.

RESULTSThere were 8 male and 15 female patients. The stone diameter were (3.2 ± 0.7) cm (range 2.1-4.0 cm). All patients did both parathyroid surgery and kidney surgery. The statistical discrepancy of serum calcium (there were (3.31 ± 0.39) mmol/L before surgery and (2.12 ± 0.18) mmol/L at 7 days after surgery, t = 11.26), serum phosphorus ((0.70 ± 0.09) and (1.21 ± 0.21) mmol/L in before and after surgery respectively, t = 10.53), iPTH (there were (28.8 ± 10.0) pmol/L before surgery and (3.6 ± 2.6) pmol/L after surgery, t = 12.83) and 24-hours urine calcium (there were (7.2 ± 3.1) mmol/d before surgery and (3.6 ± 2.5) mmol/d after surgery, t = 8.81) before and after the operation was significant (all P < 0.01). PTH concentration with serum calcium concentration correlation coefficient was r = 0.59 (P < 0.01). Eighteen patients (78.3%) had solitary parathyroid adenomas, two patients (8.7%) had multiple parathyroid adenomas, and three patients (13.0%) had multiglandular hyperplasia confirmed at surgery and histology. During follow-up, 8 patients had stone recurrence and 3 patients were did operation again to deal with renal stone within 2 years. Among them, 7 cases were normal, 1 case of parathyroid adenomas recurrence and reoperation.

CONCLUSIONSThe parathyroid operation may reduce the calculus recurrence remarkably. Early diagnosis and treatment of primary hyperparathyroidism is helpful to reduce the calculus recurrence and preserve the renal function.

OBJECTIVETo compare the safety, efficacy and complications of laparoscopic pyelolithotomy (LPL) and percutaneous nephrolithotomy (PCNL) for treatment of renal pelvic stones larger than 2.5 cm.

METHODSFrom 2011 to 2016, 32 patients underwent LPL and another 32 patients received PCNL for renal pelvic stones larger than 2.5 cm. The baseline characteristics of the patients, stone size, mean operative time, estimated blood loss, postoperative hospital stay, stone-free rate, postoperative analgesia, blood transfusion, and the intraoperative, early postoperative and long-term complications were compared between the two groups.

RESULTSThe baseline characteristics and stone size were comparable between the two groups. The mean operative time of LPL and PCNL was 117∓23.12 and 118.16∓25.45 min, respectively (P>0.05). The two groups showed significant differences in the mean estimated blood loss (63∓11.25 vs 122∓27.78 mL, P<0.01) and blood transfusion rate (0 vs 6.2%, P<0.01) but not in postoperative hospital stay (4.5∓1.34 vs 4.8∓2.2 days, P>0.05), stone-free rate (93.1% vs 87.5%, P>0.05) or the postoperative analgesia time (1.7∓0.5 and 1.9∓0.6 days, P>0.05). The incidence of intraoperative complications were significant lower in LPL group than in PCNL group (6.2% vs 25.0%, P<0.01), but the incidences of early postoperative complications (25.0% vs 34.4%, P>0.05) and long-term postoperative complications (9.4% vs 12.5%, P>0.05) were similar between them.

CONCLUSIONPCNL is the standard treatment for pelvic stones larger than 2.5 cm, but for urologists experienced with laparoscopic technique, LPL provides a feasible and safe option for management of such cases.

OBJECTIVE: To compare the outcome of mini-tract vs standard-tract percutaneous nephrolithotomy (PCNL) in staghorn calculi. METHODS: Between May 2009 and May 2011, 122 patients with renal staghorn calculi were treated by PCNL. Fifty-six patients underwent mini-PCNL and the others underwent standard-PCNL. The therapeutic effect and complication of the 2 groups were compared. RESULTS: The two groups had comparable demographic conditions. Although the operation time was significantly longer in mini-PCNL group [(126±24.5) min vs (98±18.9) min], there was no striking difference in hospital stay [(5.7±1.3) d vs (5.3±1.1) d], hemoglobin drop [(9.5±3.2) g/L vs (10.5±3.3) g/L], stone-free state before charge (91.1% vs 89.4%) and complications. CONCLUSION The efficacy and safety of mini-PCNL and standard-PCNL are not significantly different.

A 74-yr-old woman presented with fever and abdominal discomfort. She was in a septic condition caused by urinary tract infection. Her computed tomogram of the abdomen revealed features of hydronephrosis with ureteral stones in both kidneys. During percutaneous nephrostomies, right pyeloduodenal fistula (PDF) was diagnosed. Elective surgery was originally planned but the patient was in a poor condition to undergo surgery. Instead, 2 times endoscopic clipping and ligation by endoloop were applied with parenteral antibiotics for the fistula lesion. On admission day 30, she was discharged from the hospital after confirmation of no more contrast leakage on fistulography. We reviewed the literature and discuss the etiologies, clinical presentations, diagnosis, and treatment of PDF.

OBJECTIVETo evaluate the occurrence and management of complications following minimally invasive percutaneous nephrolithotomy (MPCNL).

METHODSThe data of 4326 cases of MPCNL from January 2001 to February 2006 were reviewed, including 2451 male cases and 1875 female cases. Their age ranged from 4 to 82 years with a mean of 42 years. Of 4326 cases, 1221 cases had simple nephrolithiasis, 1735 staghorn nephrolithiasis, 386 upper ureterolithiasis, 90 serious stone street after extracorporeal shock wave lithotripsy, and 894 residual calculi after open surgery.

RESULTSAmong the 4326 cases of MPCNL, complications occurred in 445 cases (10.3%). Of the 445 cases, 20 had massive hemorrhage, 13 pleural injuries, 1 colonic perforation, 343 fever attacks (T > 38 degrees C), 13 septic shocks, 16 perinephric urinoma, 9 perinephric abscess, 26 renal perforating injuries, 1 guide wire misled into inferior vena cava, 3 died.

CONCLUSIONSMPCNL is a minimally invasive operation. However, serious complications would occur if the procedure were ignored. The improvement in the prevention and management of complications can promote the application of this procedure.
