Abstract
OBJECTIVES Posttransplant anemia might be associated with cardiovascular morbidity and increased mortality. To our knowledge, the debate on anemia correction has neither been revisited nor decided definitively. We aimed to assess the effects of full correction of posttransplant anemia on the cardiovascular system and quality of life among renal transplant recipients with stable graft function who were using erythropoietin-stimulating agents. MATERIALS AND METHODS We enrolled 247 kidney recipients with stable graft function to be assessed for anemia. Eligible patients were randomized to achieve targeted hemoglobin of 11 to 12 g/dL (group 1, n = 183) or of 13 to 15 g/dL (group 2, n = 64) with the use of erythropoietin-stimulating agents. Patients underwent monthly clinical and laboratory evaluations of kidney graft function. Quality of life and echocardiography were assessed at study start and at 12 months. RESULTS The 2 groups were comparable regarding pretransplant characteristics. In group 2, we observed comparable posttransplant complications (P > .05) but better graft function at 6 months and better cardiac indexes at 1 year of the study (P < .05). At 12 months, quality of life had improved after full correction of posttransplant anemia in the renal transplant recipients who received erythropoietinstimulating agents. CONCLUSIONS Full correction of posttransplant anemia in renal transplant recipients was associated with improved quality of life and cardiac indexes without an effect on cardiovascular comorbidity.
PICO Summary
Population
Adult kidney transplant recipients with stable graft function (n= 247).
Intervention
Targeted haemoglobin of 11 to 12 g/dL with the use of erythropoietin-stimulating agents (ESA) (group 1, n= 183)
Comparison
Targeted haemoglobin of 13 to 15 g/dL with ESA (group 2, n= 64)
Outcome
Patients underwent monthly clinical and laboratory evaluations of kidney graft function. Quality of life and echocardiography were assessed at study start and at 12 months. In group 2, there were comparable post-transplant complications, but better graft function at 6 months and better cardiac indexes at 1 year of the study. At 12 months, quality of life had improved after full correction of post-transplant anaemia in the renal transplant recipients who received erythropoietin-stimulating agents.

Abstract
PURPOSE To determine the efficacy and safety of trajectory infiltration with 1:150 000 Norepinephrine (NE) in reducing blood loss during percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS This is a prospective randomized double-blinded placebo-controlled trial. In all, 140 consecutive patients underwent PCNL for the management of large renal calculi. They were randomly assigned (1:1) to one of either study groups, the NE-PCNL group (70 patients whose PCNL-trajectory was infiltrated by NE) or the Placebo group (saline PCNL) (70 patients whose PCNL tracts were infiltrated by normal saline). Procedure-related blood loss (the primary outcome) was assessed and statistically analyzed. Also, all other procedure-related events and complications were recorded and compared. RESULTS The median blood loss was 378 ml (IQR: 252-504) in the NE-PCNL group versus 592 ml (IQR: 378-756) in the S-PCNL group (p < 0.0001). In addition, Hemoglobin and Hematocrit deficits were lower in NE-PCNL (p < 0.05). Patients who were randomized to the NE-PCNL group had a higher immediate stone-free rate (SFR) (80%) compared with those of the S-PCNL group (70%) (p = 0.034). However, no statistical differences were found in the final SFR. The reported overall complications between the 2 groups were similar (p > 0.05). Indeed, bleeding-related complications were 1 (1.4%) versus 10 (14.3%) for NE-PCNL and S-PCNL, respectively (p = 0.009). CONCLUSIONS Trajectory infiltration of PCNL tracts by NE was found to be effective and safe in mitigation of PCNL-related blood loss. This step is a timeless and cost-effective as NE is readily available in surgical theaters and of very low cost.
PICO Summary
Population
Patients undergoing percutaneous nephrolithotomy (PCNL) (n= 140).
Intervention
PCNL after tract infiltration with norepinephrine (NE) (NE-PCNL group, n= 70).
Comparison
PCNL after tract infiltration with normal saline (S-PCNL group, n= 70).
Outcome
The primary outcome was procedure-related blood loss. The median blood loss was 378 ml (IQR= 252, 504) in the NE-PCNL group versus 592 ml (IQR= 378, 756) in the S-PCNL group. Haemoglobin and haematocrit deficits were lower in NE-PCNL. Patients in the NE-PCNL group had a higher immediate stone-free rate (80%) compared with those of the S-PCNL group (70%). No statistical differences were found in the final stone free rate. The reported overall complications between the two groups were similar. Bleeding-related complications were 1 (1.4%) versus 10 (14.3%) for NE-PCNL and S-PCNL, respectively.
