RESUMO
PURPOSE: This study aimed to determine the effect of adrenal mass functionality and different hormone subtypes synthesized by the adrenal masses on laparoscopic adrenalectomy (LA) outcomes. MATERIALS AND METHODS: The study included 298 patients, 154 of whom were diagnosed with nonfunctional masses. In the functional group, 33, 62, and 59 patients had Conn syndrome, Cushing's syndrome, and pheochromocytoma, respectively. The variables were analyzed between the functional and nonfunctional groups and then compared among functional masses through subgroup analysis. RESULTS: The incidence of diabetes mellitus, hypertension, and obesity, blood loss, and length of hospital stay (LOH) were significantly higher in the functional group than in the nonfunctional group. In the subgroup analysis, patients with pheochromocytoma had significantly lower body mass index but significantly higher mass size, blood loss, and LOH than the other two groups. A positive correlation was found between mass size and blood loss in patients with pheochromocytoma (p ≤ 0.001, r = 0.761). However, no significant difference in complications was found among the groups. CONCLUSIONS: In this study, patients with functional adrenal masses had higher comorbidity rates and American Society of Anesthesiologists scores. Moreover, blood loss and LOH were longer on patients with functional adrenal masses who underwent LA. Mass size, blood loss, and LOH in patients with pheochromocytoma were significantly longer than those in patients with other functional adrenal masses. Thus, mass functionality did not increase the complications.

Holmium: YAG (Ho: YAG) laser lithotripsy with flexible ureterorenoscopy can be used with high stone-free and low complication rates for renal stones. This study aimed to determine the factors affecting the total laser energy in cases with provided stone-free status after a single session of retrograde intrarenal surgery (RIRS). Data of 222 patients who underwent RIRS between October 2017 and March 2020 were evaluated retrospectively. After exclusion criteria, the study was carried out with 184 stone-free cases. All cases were performed without using a ureteral access sheath (UAS), and dusting was preferred as the lithotripsy method. The effects of age, gender, body mass index (BMI), previous RIRS history, previous shock wave lithotripsy (SWL) history, stone localization, number of stones, stone surface area, and stone density on total laser energy were analyzed. There was no significant correlation between total laser energy with gender, BMI, previous RIRS history, previous SWL history, stone localization, and the number of stones (p:0.347, p:0.482, p:0.119, p:0.167, p:0.907, p:0.933 respectively). There was a significant correlation between age and total laser energy (p = 0.032), but it was not observed when the effect of the stone surface area was removed (p = 0.354). There were significant correlations between total laser energy and stone surface area, stone density, and total laser time (p<0.001, p<0.001, and p <0.001, respectively). Stone area and stone density affect the total energy consumed during laser lithotripsy. Urologists should consider the stone area, stone density, and the power of the laser device to determine which surgical technic to prefer.

Estrogen receptors in prostate cancer (PCa) are a subject of debate. The aim of the present study was to investigate whether estrogen receptor-α (ERα) and estrogen receptor-ß (ERß) impact the biochemical recurrence (BCR) of non-metastatic PCa after surgery. Following the application of the exclusion criteria, data from 108 patients who underwent laparoscopic radical prostatectomy between January 2011 and December 2019 were retrospectively evaluated. A total of 36 patients with BCR constituted the BCR group. The control group was formed using the Propensity Score Matching (PSM) method with a 1:2 ratio, including parameters with well-studied effects on BCR. The median follow-up time was 74.3 (range, 30-127.5) months in the BCR group and 66.6 (range, 31.5-130) months in the control group. Pathology specimens from the two groups were immunohistochemically stained with ERα and ERß antibodies. Logistic regression analysis and survival analysis were performed. No differences in clinicopathological characteristics were detected between the two groups. The patients with ERα(-)/ERß(+) staining results had a significantly fewer BCRs than other patients (P=0.024). In the logistic regression analysis, patients with ERα(-)/ERß(+) PCa also had a significantly lower risk of recurrence (P=0.048). In the survival analysis, the 5-year BCR-free survival rate of patients with ERα(-)/ERß(+) PCa was higher than that of other patients (85.7 vs. 66.1%; P=0.031). Excluding the effects of well-studied risk factors for recurrence by the PSM method, the present study showed that ERα and ERß have prognostic value for non-metastatic PCa. The 5-year BCR-free survival rate is significantly higher in patients whose PCa tissue has ERα(-)/ERß(+) staining results.
RESUMO
OBJECTIVES: The primary objective of this study was to evaluate the impact of monocyte-to-high-density lipoprotein cholesterol ratio on all-cause mortality in deceased donor kidney transplant recipients. MATERIALS AND METHODS: This was a retrospective observational study in which all deceased donor kidney transplant recipients were included. Relevant data for analyses included clinical and demographic features, laboratory values, number of HLA matches, occurrence of delayed graft function, cold ischemia time, and survival status. Kaplan-Meier survival analysis and Cox proportional hazards analysis were performed to determine the effects of monocyte-to-high-density lipoprotein cholesterol ratio on all-cause mortality. RESULTS: Our study included 325 deceased donor kidney transplant recipients (43.1% females, mean age of 44.5 ± 11.2 years). Median value of monocyte-to-high-density lipoprotein cholesterol ratio was 14.0 (interquartile range, 9.94-21.03). The total median observation time was 227 weeks (range, 115-345 weeks). Twenty deaths (12.3%) occurred during the follow-up period in recipients with monocyte-to-highdensity lipoprotein cholesterol ratio below median value, whereas 47 deaths (29%) occurred in recipients with ratio above the median (P < .001). Log-rank test showed significantly higher mortality in the group with monocyte-to high density lipoprotein cholesterol ratio higher than median (P = .001). In the multivariate Cox model, delayed graft function, duration of dialysis, cold ischemia time, and monocyte-to-high-density lipoprotein cholesterol ratio group appeared as independent predictors of all-cause mortality. CONCLUSIONS: Monocyte-to-high-density lipoprotein cholesterol ratio before kidney transplant seems to affect survival independently in deceased donor kidney transplant recipients.

Background: Holmium:yttrium-aluminium-garnet (Ho:YAG) laser lithotripsy with ureteroscopy (URS) was a safe and successful treatment option for pediatric ureteral stones. We aimed to comparatively evaluate the outcomes of 15 and 30 W Ho:YAG laser lithotriptors in pediatric ureter stones. Materials and Methods: We retrospectively evaluated 55 children who underwent ureteroscopic laser lithotripsy to treat ureter stone size up to 15 mm between September 2009 and March 2020. Groups were formed according to the laser lithotriptor power 15 W (Group 15: n = 32), 30 W (Group 30: n = 23). The efficiency of laser lithotriptors was compared between the groups. Results: The age, gender, and stone characteristics (longest stone diameter, density, location and multiple stones) were similar between the groups. In the postop first month, stone-free status was achieved in all cases except one child in Group 15. The median operative time was significantly shorter in Group 30 (40 minutes) than in Group 15 (52.5 minutes) (P = .010). Clavien-Dindo class (CDC) 2 complications occurred in 2 children in both groups (P = .597). Although ureteric stenosis was observed in 1 patient in Group 15, no ureteric stenosis was seen in Group 30 during follow-up (median 16.1 months). Length of hospital stay (LoHS) and stone-free rates were similar between groups. Conclusion: URS with 15 and 30 W Ho:YAG laser lithotriptors is an effective treatment option for pediatric ureteral stones with a high success rate and low complication rates. In brief, 30 W Ho:YAG laser lithotriptors should be preferred over 15 W lithotriptors due to their shorter operative time with similar success rate.

OBJECTIVE: This study aimed to compare the right and left side laparoscopic donor nephrectomy (LDN) outcomes of a single center. MATERIALS AND METHODS: The outcomes of patients who underwent LDN in our clinic between 2008 and 2020 were evaluated retrospectively. Two groups were consisted according to the side of the donor kidney. The gender, age, body mass index, duration of operation, amount of bleeding, warm ischemia time, drain removal time, and duration of hospitalization and complications were compared between groups. RESULTS: A total of 314 patients were included in the study. Sixty-six patients underwent right LDN and 248 underwent left LDN. There was no difference between groups in terms of age, duration of operation, amount of bleeding, warm ischemia time, and complications (p>0.05). However, drain removal time and duration of hospitalization were longer in the left LDN group (p<0.05). CONCLUSIONS: The right LDN had similar intraoperative outcomes with the left LDN. However, failure on meticulous dissection of the lymphatic structures during left LDN might cause chylous drainage and prolonged hospitalization time.
