Comparison of UW and Celsior: long-term results in kidney transplantation.

BACKGROUND: The aim of this study was to compare 2 preservation solutions in kidney transplant recipients in the same center during the same period since initiation of the use of High Na+; low K+ solution (Celsior). MATERIAL AND METHODS: From January 1999 to April 2011, 610 consecutive renal transplantations were done in our department with deceased donor kidneys. Data were collected prospectively. Organ procurement was performed in our center for 305 kidneys. We washed and preserved 409 kidneys in UW, and 201 in Celsior solution. RESULTS: Donors criteria were worse in the Celsior group for age, male sex, creatinemia, and cold ischemia. Populations of recipients were comparable. There were no differences at 1 and 12 months in creatinine levels (p=0.9 and 0.8, respectively) and in number of delayed graft functions (DGF) (p=0.8 and relative risk =0.9) between groups. There were no differences in post-transplantation outcomes for all variables. At 5 years, graft survival was 90.4% for UW and 93.5% for Celsior (p=0.44). CONCLUSIONS: Our retrospective study did not succeed in demonstrating superiority of a High Na+; low K+ solution compared to a UW type reference solution. Celsior has the same effectiveness as UW during kidney cold storage.

The high rate of de novo graft carcinomas in renal transplant recipients.

BACKGROUND: To investigate the incidence, the clinical characteristics and outcomes of renal graft carcinomas in the same renal transplant population. METHODS: From April 1989 to April 2012, 1,037 consecutive renal transplantations were performed in our department. Data were collected prospectively in an extensively maintained database. For all recipients, monitoring consisted of clinical examination and an abdominopelvic CT scan or ultrasonography at least once a year. RESULTS: After 1,037 renal transplantations, 48 men and 14 women (sex ratio 3:4) with a mean age of 54 years (25.1-78.9) were included for urological malignancies. Eight graft carcinomas were identified: 7 renal cell carcinomas (5 papillary carcinomas and 2 clear cell carcinomas of the renal graft) and 1 transitional cell carcinoma of the ureteral graft (incidence 0.78%). Nephron-sparing surgery was chosen for 5 patients with good outcomes. All graft renal cell carcinomas were classified as pT1a and the mean size of tumors was 28.4 mm (range 6-45). The 5-year specific survival rate was 100%. No recurrence was observed with a mean follow-up of 36.8 months (4.1-84.3). CONCLUSION: Thus confirming an increased risk of de novo graft cancer, close monitoring of renal transplant recipients should be discussed with at least an abdominopelvic ultrasonography and PSA measurement once a year. Renal cell graft carcinomas seemed to be mostly small and of papillary type and low grade.

Impact of renal graft nephrectomy on second kidney transplant survival.

PURPOSE: To determine the impact of non-functional renal graft nephrectomy on second kidney transplantation survival. METHODS: We performed a retrospective study on patients managed in our department from April 1989 to April 2011. We compared the number of acute graft rejections and graft survival between patients undergoing second transplantation with (Group I) or without (Group II) prior graft nephrectomy. RESULTS: A total of ninety-one patients received a second renal graft: 43 underwent graft nephrectomy and 48 kept their non-functional renal graft. There were 5 episodes of acute graft rejection in Group I and 12 in Group II (p = 0.3). Six (13.9 %) grafts failed in Group I and eight (16.6 %) in Group II. Five and 10 years actuarial graft survival in Group I were, respectively, 91 and 85 %, while in Group II were 82.7 % and 69 % (p = 0.2). PRA level and number of acute rejection episodes did not have a statistically significant influence on graft survival, whether the patient had a nephrectomy or not (p = 0.2). CONCLUSION: Nephrectomy of a failed allograft did not significantly improve the survival of a subsequent graft. Graft nephrectomy should be indicated in case of graft-related pain or a chronic inflammation syndrome.

[Haemospermia due to seminal vesicle amyloidosis. Treatment by laparoscopic vesiculectomy. A case report]. / L'hémospermie par amylose des vésicules séminales. Traitement par vésiculectomie coelioscopique. A propos d'un cas.

Amyloidosis of the seminal vesicles is a rare cause of haemospermia. The authors report the case of a 42-year-old patient with recurrent haemospermia over a period of 2 years and abnormalities of one seminal vesicle on ultrasonography and MRI, justifying laparoscopic resection. Histological examination demonstrated localized amyloidosis, secondary to inflammation. No recurrence was observed with a follow-up of one.
