PURPOSE: Bacteremia is a major infectious complication associated with mortality in liver transplant recipients. The causative organisms and clinical courses differ between medical centers due to variations in regional bacterial epidemiology and posttransplant care. Further, living donors in Korea contribute to 83% of liver transplants, and individualized data are required to improve survival rates. PATIENTS AND METHODS: We retrospectively analyzed 104 subjects who had undergone living-donor liver transplant from 2005 to 2007. RESULTS: Among the 144 consecutive living-donor liver transplant recipients, 24% (34/144) developed bacteremia, 32% (46/144) developed non-bacteremic infections, and 44% (64/144) did not develop any infectious complications. Forty episodes of bacteremia occurred in 34 recipients. The major sources of bacteremia were intravascular catheter (30%; 12/40), biliary tract (30%; 12/40), and abdomen (22.5%; 9/40). Gram-positive cocci were more common (57.5%; 23/40) than Gram-negative rods (32.5 %; 13/40) and fungi (10%; 4/40). The data revealed that the following factors were significantly different between the bacteremia, non-bacteremic infection, and no infection groups: age (p = 0.024), posttransplant hemodialysis (p = 0.002), ICU stay (p = 0.012), posttransplant hospitalization (p < 0.0001), and duration of catheterization (p < 0.0001). The risk factors for bacteremia were older than 55 years (odds ratio, 6.1; p = 0.003), catheterization for more than 22 days (odds ratio, 4.0; p = 0.009), UNOS class IIA (odds ratio, 6.6; p = 0.039), and posttransplant hemodialysis (odds ratio, 23.1; p = 0.001). One-year survival rates in the bacteremic, non-bacteremic infection, and no infection groups were 73.2%, 91.3%, and 93.5%, respectively. CONCLUSION: Early catheter removal and preservation of renal function should focus for improving survival after transplant.

OBJECTIVETo investigate the risk factors of postoperative urinary retention after rectal cancer surgery.

METHODSClinical data of 133 patients with rectal cancer undergoing radical surgery from January 2013 to September 2014 in the General Hospital of the PLA Rocket Force were retrospectively analyzed. Time to the first removal of urinary catheter, incidence of postoperative urinary retention, and time to re-insert indwelling catheter were recorded. Risk factors of urinary retention were analyzed.

RESULTSOf 133 patients, 70 were males and 63 were females, with a median age of 62 (20-79) years old. Distance from tumor lower margin to anal verge were ≤5 cm in 58 patients, >5 cm to 10 cm in 41 patients, and >10 cm to 15 cm in 34 patients. The postoperative TNM stage was recorded in 35 patients with stage I(, 34 with stage II(, 59 with stage III( and 5 with stage IIII(. Surgical procedures included anterior resection (AR) for 92 patients, abdominoperineal resection (APR) for 25 patients and intersphincteric resection (ISR) for 16 patients. Laparoscopic approach was performed in 89 patients compared with open operation in 44 patients. Time to the first removal of urinary catheter was 2-7 days after operation (median, 5 days) and 36 (27.1%) patients developed urinary retention. All the 36 patients achieved spontaneous voiding by re-inserting urinary catheter for 2-28 days (median, 6 days). Univariate analysis showed that elderly (>65 years) and laparoscopic approach had significantly higher incidence of urinary retention [37.5%(21/56) vs. 19.5%(15/77), χ=5.333, P=0.021; 34.8%(31/89) vs. 11.4%(5/44), χ=8.214, P=0.004; respectively]. Multivariate logistic analysis demonstrated that old age(OR=3.949, 95%CI:1.622 to 9.612, P=0.002), laparoscopic approach (OR=5.665, 95%CI:1.908 to 16.822, P=0.002), and abdominoperineal resection (OR=3.443, 95%CI:1.199 to 9.887, P=0.022) were independent risk factors of urinary retention after rectal cancer surgery.

CONCLUSIONSPatients undergoing rectal cancer surgery have a high risk of postoperative urinary retention. More attention should be paid to the old patients, especially those undergoing laparoscopic procedure or abdominoperineal resection, to prevent postoperative urinary retention and urinary dysfunction.

BACKGROUNDSimultaneous pancreas-kidney transplantation (SPKT) frees the diabetic patient with end-stage nephropathy from dialysis and daily insulin injections. Herein, we review consecutive cases of SPKT with bladder drainage performed at our institution over an 8-year period.

METHODSThe study population included 21 patients (16 males and 5 females) who underwent SPKT between September 2001 and September 2009. Seven patients had type-1 diabetes and 14 had type-2 diabetes. Nineteen patients were on dialysis at the time of transplantation. Donation after cardiac death donors were selected for SPKT. The mean human leukocyte antigen match was 2 (range 0 - 4). SPKT was always performed using bladder drainage and vascular anastomoses to the systemic circulation. Immunosuppressive treatment consisted of anti-lymphocyte globulin induction followed by tacrolimus, mycophenolate mofetil, and prednisone.

RESULTSThe mean hospital stay was 45.43 days. After a mean follow-up of 39.4 months, survival rates for patient, kidney, and pancreas were 76.2%, 76.2%, and 66.7% at 1 year; 76.2%, 59.3%, and 55.6% at 5 years; and 57.1%, 39.5%, and 41.7% at 8 years, respectively. Major complications included anastomotic leaks, reflux pancreatitis, and rejection. Six patients died from septic shock (n = 3), duodenal stump leak (1), cardiac arrest (1), or renal failure (1). Eight kidney grafts were lost due to acute rejection (n = 2), chronic rejection (3), and death with a functioning graft (3). Pancreatic graft failure (9) was caused by thrombosis (n = 1), rejection (2), duodenal stump leak (1), and death with a functioning graft (5).

CONCLUSIONSSPKT is a valid therapeutic option for uremic diabetics although few hospitals in China can undertake SPKT.

Objective: To compare the clinical effect of diode laser enucleation of the prostate (DIOD) with that of transurethral resection of the prostate (TURP) on benign prostate hyperplasia (BPH) with different prostate volumes. METHODS: This retrospective study included 256 BPH patients treated by DIOD (n = 141) or TURP (n = 115) from March 2012 to August 2015. According to the prostate volume, we divided the patients into three groups: <60 ml (42 for DIOD and 31 for TURP), 60－80 ml (51 for DIOD and 45 for TURP), and >80 ml (48 for DIOD and 39 for TURP). We obtained the relevant data from the patients before, during and at 6 months after surgery, and compared the two surgical strategies in operation time, perioperative levels of hemoglobin and sodium ion, post-operative urethral catheterization time and bladder irrigation time, pre- and post-operative serum PSA levels, International Prostate Symptoms Score (IPSS), post-void residual urine (PVR) volume and maximum urinary flow rate (Qmax), and incidence of post-operative complications among different groups. RESULTS: In the <60 ml group, there were no remarkable differences in the peri- and post-operative parameters between the two surgical strategies. In the 60－80 ml group, DIOD exhibited a significant superiority over TURP in the perioperative levels of hemoglobin (［3.25 ± 1.53］ g/L vs ［4.77 ± 1.67］ g/L, P <0.05) and Na+ (［3.58 ± 1.27］mmol/L vs ［9.67 ± 2.67］ mmol/L, P <0.01), bladder irrigation time (［30.06 ± 6.22］h vs ［58.32 ± 10.25］ h, P <0.01), and urethral catheterization time (［47.61 ± 13.55］ h vs ［68.01 ± 9.69］ h, P <0.01), but a more significant decline than the latter in the postoperative PSA level (［2.34 ± 1.29］ ng/ml vs ［1.09 ± 0.72］ ng/ml, P <0.05), and similar decline was also seen in the >80 ml group (［3.35 ± 1.39］ ng/ml vs ［1.76 ± 0.91］ ng/ml, P <0.05). No blood transfusion was necessitated and nor postoperative transurethral resection syndrome or urethral stricture observed in DIOD. However, the incidence rate of postoperative pseudo-urinary incontinence was significantly higher in the DIOD (22.7%, 32/141) than in the TURP group (7.83%, 9/115) (P <0.05). CONCLUSIONS DIOD, with its obvious advantages of less blood loss, higher safety, faster recovery, and more definite short-term effectiveness, is better than TURP in the treatment of BPH with medium or large prostate volume and similar to the latter with small prostate volume.
