ABSTRACT
Objective To observe the effects of modified Jianpi Yishen Decoction on urinary osteopontin (OPN) in calcium oxalate nephrolithiasis patients after percutaneous nephrolithotomy (PCNL) or ureteroscope lithotomy (URL);To clarify the mechanism of modified Jianpi Yishen Decoction on the prevention of calcium oxalate kidney stones. Methods Totally 116 calcium oxalate nephrolithiasis patients were randomly divided into trial group (62 cases) and control group (54 cases). The trial group took modified Jianpi Yishen Decoction every other day, while the control group took potassium sodium hydrogen citrate granules three times a day. The concentrations of OPN, urinary calcium and urinary oxalic acid of the patients in the two groups were observed before treatment and 2 weeks and 4 weeks of treatment. Results The concentration of urinary OPN of 2 weeks and 4 weeks of the treatment in the trial group was significantly increased compared with before treatment (P0.05). The differences in the concentrations of urinary calcium and urinary oxalic acid of the two groups between before and after treatment were not significant (P>0.05). Conclusion Modified Jianpi Yishen Decoction can effectively restrain the formation of the calcium oxalate stones by increasing the level of urinary OPN, which demonstrates effective prevention in the calcium oxalate nephrolithiasis patients after PCNL or URL.
ABSTRACT
Objective To evaluate the efficacy and application value of retroperitoneal laparoscopic nephroureterectomy for localized and poor differentiated renal pelvic carcinoma by comparing with open nephroureterectomy.Methods Thirty-three pelvic carcinoma patients underwent radical nephroureterectomy were retrospeetively analyzed.All tumors were confirmed to be localized,stage T1-T3 and grade 3.Retroperitoneal laparoscopic nephroureterectomy was performed in 12 patients,the ureteral orifice was resected in traditional way through a small incision in lower abdomen.Open radical nephroureterectomy was performed in 21 cases.Clinical outcomes of the patients were compared between the 2 surgery groups.Results Mean operative time was 232 vs 212 min(P=0.100)and blood loss volume was 162 vs 233 ml(P=0.001)in the laparoscopic and open nephroureterectomy groups.Mean postoperative hospitalization was 7.6 vs 9.8 d(P＜0.001)for the laparoscopic and open groups.During the followup for 7-67 months,all the 33 patients survived.There was no recurrence or metastasis in laparoscopic group.While there was 1 retroperitoneal recurrence,and 3 cases suffering from superficial bladder cancer in open surgery group.Conclnsion Retroperitoneal laparoscopic nephroureterectomy may be performed safely in local renal pelvic carcinoma patients with poor differentiated tumors,with less intraoperative blood loss and early recovery.
