OBJECTIVETo improve the diagnosis and treatment of testicular torsion.

METHODSThe clinical features of 49 testicular torsion patients admitted to Department of Urology Nanjing Drum Tower Hospital from April 2008 to March 2014 were retrospectively analyzed, the average age was (21 ± 6) years (range 13-52 years).Forty-four cases underwent the color Doppler flow imaging of scrotum, demonstrated reduction of the testicular blood supply in 9 cases and loss of the testicular blood supply in 35 cases. Orchiectomy or orchiopexy was performed according to the testicular blood supply, the contralateral testis fixation was performed in all patients. A two-tailed Student's t-test was used to compare the data between two groups, Pearson correlation analysis was used to analyze the correlation of diurnal temperature and number of cases.

RESULTSAll the patients with testicular torsion were Tunica-reversed, 38 (77.5%) cases occurred from November to April. The monthly incidence of testicular torsion was positively correlated with diurnal temperature (r = 0.6434, P = 0.024). Forty-four cases underwent the color Doppler flow imaging, demonstrated the reduction or loss of the testicular blood supply, and these patients were confirmed to be testicular torsion by surgical exploration. The salvage rates of testis in patients with testicular torsion were 2/2, 5/15, 2/9 and 4.2% (1/24) in those seeking medical attention within 6, 12, 24 hours and over 24 hours after the onset of pain. All the patients were followed up for 3 to 75 months, and no one experienced recurrent torsion.

CONCLUSIONSThe incidence of testicular torsion is higher during the spring and winter, diurnal temperature change is associated with testicular torsion. The diagnostic rate of color Doppler flow imaging is high, which can be chosen as the primary method. Prompt recognition and treatment are necessary for testicular salvage.

OBJECTIVETo analyze the results of transperitoneal and retroperitoneal laparoscopic ureteroureterostomy procedure in the treatment of patients with retrocaval ureter.

METHODSFrom May 2004 to December 2012, 18 patients including 12 male and 6 female patients were operated for retrocaval ureter, the average age was (37 ± 10) years (range 17-55 years). Eight patients underwent transperitoneal laparoscopic ureteroureterostomy (transperitoneal laparoscopic group), and the other 10 patients' laparoscopic procedure were performed via retroperitoneal approach(retroperitoneal laparoscopic group). These patients' records were retrospectively analyzed for perioperative characteristics, complications and follow-up results. A two-tailed Student's t-test was used to compare perioperative data between the two groups.

RESULTSTechnical success was acquired in all 18 laparoscopic procedures. Mean operative time of transperitoneal and retroperitoneal laparoscopic group was (85 ± 20) minutes (60-130 minutes) and (98 ± 30) minutes (70-180 minutes) , respectively. There was no difference in operation time between the two groups (t = 1.03, P > 0.05). The blood loss was less than 50 ml in all the patients. Comparison of anal exhaust time between the two groups showed no statistic difference (t = 0.16, P > 0.05). No perioperative complication was observed. Intravenous pyelography or CT urography 3 months after the operation revealed a widely patent anastomosis with considerable improvement in hydronephrosis in all patients. There was no recurrence at a mean follow up of (40 ± 24) months (range 12-115 months).

CONCLUSIONBoth transperitoneal and retroperitoneal laparoscopic ureteroureterostomy are effective and minimally invasive surgical alternative for the management of retrocaval ureter.
