Influence of the median lobe on the results at 4 years of the prostate vaporization by GreenLight laser.

OBJECTIVE: The aim of this study was to examine the influence of a median lobe (ML) on complications and functional results after 4 years of GreenLight photoselective vaporization of the prostate (PVP). METHODS: All men undergoing GreenLight PVP for benign prostatic hyperplasia were included in the baseline analysis and followed prospectively. Two groups were formed according to the presence or absence of the prostatic ML. Complications classified according Clavien and Dindo and functional results (International Prostate Symptom Score [IPSS], quality of life, maximum urinary flow rate [Qmax], and postvoid residual [PVR]) were evaluated with 4 years of follow-up. The pre- and postoperative data were compared by a chi-square test (χ2 ) for the qualitative variables and by a Student t test for the quantitative variables. RESULTS: A total of 432 patients (172 with ML and 260 without ML) were included prospectively from September 2005 to October 2013. The initial populations were comparable. At 4 years of follow-up, the improvement in mean IPSS was significantly greater for patients with ML at 6, 12, 24, and 48 months. The improvement in Qmax was significantly greater for patients with ML at 1, 6, 24, and 48 months. There was no significant difference between the two groups concerning the PVR reduction, the occurrence of complications, the level of average prostate-specific antigen, and the average ultrasound volume at 4 years. CONCLUSION: There is a clearer and longer-lasting improvement in urinary symptoms in patients with prostatic ML. The indication of PVP in those patients seems to be excellent, with good results persisting at 4 years.

Renal outcome after simultaneous heart and kidney transplantation.

Simultaneous heart-kidney transplant (HKTx) is a valid treatment for patients with coexisting heart and renal failure. The aim of this study was to assess renal outcome in HKTx and to identify predictive factors for renal loss. A retrospective study was conducted among 73 HKTx recipients: Donors' and recipients' records were reviewed to evaluate patients' and renal transplants' survival and their prognostic factors. The mean follow-up was 5.36 years. Renal primary non-function occurred in 2.7%, and complications Clavien IIIb or higher were observed in 67.1% including 16 (22%) postoperative deaths. Five-year overall survival and renal survival were 74.5% and 69.4%. Among survivors, seven returned to dialysis during follow-up. The postoperative use of ECMO (HR = 6.04, P = 0.006), dialysis (HR = 1.04/day, P = 0.022), and occurrence of complications (HR = 31.79, P = 0.022) were independent predictors of postoperative mortality but not the history of previous HTx or KTx nor renal function prior to transplantation. History of KTx (HR = 2.52, P = 0.026) and increased delay between the two transplantations (HR = 1.25/hour, P = 0.018) were associated with renal transplant failure. HKTx provides good renal transplant survival and function, among survivors. Early mortality rate of 22% underlines the need to identify perioperative risk factors that would lead to more judicious and responsible allocation of a scarce resource.
