Clarithromycin was administered intravenously to 55 rabbits to evaluate its effect on experimental sepsis caused by multidrug-resistant Pseudomonas aeruginosa. Acute pyelonephritis was induced after ligation of the right ureter and injection of 10(8) CFU of the test isolate per kg of body weight into the renal pelvis. The animals were divided into six groups: group A, controls; group B, rabbits that received one intravenous dose of 80 mg of clarithromycin per kg concomitantly with bacterial challenge; group C, rabbits that received two doses of clarithromycin, the second one of which was given 2 h after the first one; group D, rabbits that received 15 mg of amikacin per kg; group E, rabbits that received one dose of clarithromycin and amikacin; and group F, rabbits that received two doses of clarithromycin and amikacin. Serum endotoxin levels were estimated by the QCL-1000 Limulus amoebocyte lysate assay, tumor necrosis factor alpha (TNF-alpha) levels were measured by a bioassay, and malondialdehyde (MDA) levels were measured by the thiobarbiturate assay. Viable bacterial counts in various tissue samples were also assessed. The mean survival times of the animals in groups A, B, C, D, E, and F were 4.50, 7.69, 4.07, 4.55, 11.55, and 11.60 days, respectively (P = 0.033 for group D versus group F, P = 0.006 for group D versus group E, P = not significant for group B versus group E, P = 0.042 for group C versus group F). Serum endotoxin levels were similar between groups at all sampling times; TNF-alpha and MDA levels in groups B, C, E, and F decreased significantly over follow-up. The numbers of viable bacterial cells in the infected kidney were similar among the groups; those in the liver, spleen, lungs, and mesenteral lymph nodes were significantly decreased in groups B, E, and F compared to those in groups A and D. It is concluded that a prolongation of survival in animals with experimental sepsis caused by multidrug-resistant P. aeruginosa was achieved after coadministration of clarithromycin and amikacin and that the increased survival was probably attributable to the immunomodulatory properties of clarithromycin.

The aim of the present study was to demonstrate that the treatment outcome of transperitoneal ureterocutaneostomy using the transverse mesocolon is not inferior to that of conventional retroperitoneal ureterocutaneostomy. The enrolled subjects were 26 patients who underwent ureterocutaneostomy among a total of 160 cases of urinary diversion performed at our institution between March, 2004 and November, 2011. A total of 11 cases and 18 ureters were treated by transperitoneal ureterocutaneostomy via the transverse mesocolon, with 7 bilateral ureterocutaneostomy cases. All the cases of retroperitoneal ureterocutaneostomy were unilateral, totaling 15 patients and 15 ureters. Postoperative adverse events (ileus, acute pyelonephritis), catheter-free status and renal function [blood urea nitrogen (BUN) and serum creatinine (Cr) values] were retrospectively evaluated between the groups treated by the different surgical procedures. Ileus was only observed in 1 case and improvement was achieved through conservative therapy alone (P=0.827). Acute pyelonephritis developed in 3 (27.3%) transperitoneal and 8 (53.3%) retroperitoneal cases, with all the cases recovering following treatment with antibiotics alone (P=0.199). A catheter-free status was achieved in 3 cases (27.3%) and 4 ureters (22.2%) in the transperitoneal group and in 2 cases and 2 ureters (13.3%) in the retroperitoneal group (P=0.393). There was no significant change in renal function (BUN and serum Cr values) in the transperitoneal ureterocutaneostomy cases at the postoperative, early postoperative (1 month following surgery) or the final follow-up examination (P=0.739 and 0.078). In conclusion, transperitoneal ureterocutaneostomy allows for the construction of a cutaneous stoma using a shorter ureter, with a treatment outcome that is comparable to that of retroperitoneal ureterocutaneostomy.
