    Background: Pancreas transplantation methods, such as simultaneous pancreas-kidney (SPK) transplantation and pancreas-after-kidney (PAK) transplantation, have become the most important treatments for patients with type-1 diabetes mellitus (DM)-related end-stage renal diseases (ESRD). The purpose of the study was to compare the clinical results of the pancreas graft in patients after SPK and PAK transplantations and to present the findings of our 5-year follow-up. Material/Method: A total of 55 patients who had kidney and pancreas transplantation between February 2003 and December 2010 were included in the study. The patients were divided into 2 groups based on the timing of the pancreas transplantation: SPK (n=21) and PAK (n=34). Result: The patients in the SPK group consisted of 13 males and 8 females, with a mean age of 33.6 +/- 6.8 years; whereas 25 males and 9 females formed the PAK group, with a mean age of 32.0 +/- 6.0 years. In the early postoperative period, the SPK group had 3 patients with vascular thrombosis (2 venous, 1 arterial) and the PAK group had 7 patients with thrombosis (4 venous, 3 arterial) (p=0.319). At the end of the 5-year follow-up, the patient, kidney and pancreas survival rates in the SPK group were 95.2%, 95.2%, and 61.9% respectively, and the corresponding values in the PAK group were 97%, 91.2%, 61.8% (p=0.382, p=0.504, p=0.927). Conclusions: We concluded that PAK is just as effective as SPK to prevent the destructive effects of DM when the waiting time for SPK is long and a potential live donor is present.

    Surgical correction of vesico-ureteric reflux for recurrent febrile urinary tract infections after kidney transplantation
    (Wiley, 2013) Dinckan, Ayhan; Aliosmanoglu, Ibrahim; Kocak, Huseyin; Gunseren, Filiz; Mesci, Ayhan; Ertug, Zeki; Yucel, Selcuk
    Objective To evaluate the outcome of anti-reflux revision surgery in patients diagnosed with at least a grade 3 reflux at voiding cysto-urethrography in patients with recurrent urinary tract infection (UTI) after renal transplantation. Patients and Methods We identified 60 patients with a diagnosis of recurrent febrile UTI and post-transplantation vesico-ureteric reflux (VUR) who underwent open surgical correction of reflux. Patient characteristics, including the aetiology of end-stage renal disease, age, time to VUR correction, type of VUR correction, serum creatinine levels, and number of UTIs before and after correction were documented. Results The median (range) age of the patients was 31.5 (9-65) years. A total of 30 patients underwent uretero-ureterostomy or pyelo-ureterostomy and 30 underwent extravesical or intravesical ureteric reimplantation. The median (range) creatinine levels before and after correction were 1.5 (0.8-4.5) mg/dL and 1.3 (0.7-4.5) mg/dL (P<0.05), respectively. The median (range) number of UTI episodes reported before the correction surgery was 4 (3-12), whereas number of UTI episodes after the surgery was 1 (0-12), the difference being significant (P<0.05). ConclusionsOpen surgical correction of post-transplant VUR is an effective and safe method of decreasing UTI episodes and stopping reflux. Surgical correction of reflux may prolong the life of the renal graft.
