The effect of mass functionality on laparoscopic adrenalectomy outcomes.

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.

Comparison of laparoscopic pyelolithotomy and retrograde intrarenal surgery in the management of large renal pelvic stones.

BACKGROUND: To compare the clinical outcomes of laparoscopic pyelolithotomy (LP) and retrograde intrarenal surgery (RIRS) in the management of large renal pelvic stones. PATIENTS AND METHODS: This study included patients who presented with a single renal pelvic stone sized ≥20 mm and who were treated primarily by LP or RIRS. The patients were grouped based on the surgical procedure they underwent. We retrospectively examined and compared the age, the longest axis, and the surface area of the stone, operation time, hospitalization time, complications, and stone-free rates of the two groups. RESULTS: Of the 156 patients included in the study, 44 had LP, and 112 had RIRS. Patients who received LP (13 males, 31 females) had a median age of 54 (18-79) years, while those who underwent RIRS (46 males, 66 females) had a median age of 54.5 (18-79). Patients who received LP were found to have larger median stone size (30 mm vs 24 mm, P = .003), longer operation time (100 minutes vs 70 minutes, P = .007), lower complication rate (2% vs 8.9%, P = .063), longer median hospital stay (3 days vs 1 day, P < .001) and better stone-free rate at the third month (90.9% vs 67.9%, P < .001). CONCLUSION: LP is a safe and efficient procedure that could be used as an alternative to RIRS in managing large renal pelvic stones.

A cut-off value for the operation time and other risk factors in terms of the infection risk for flexible ureterorenoscopy.

OBJECTIVES: To investigate the operation time (OT) and ureteral access sheath (UAS) usage with the infection rates and to determine a cut-off value for OT. METHODS: We retrospectively analysed the data of the patients who underwent flexible ureterorenoscopy (FURS) for renal stones larger than 20 mm between 2010 and 2019. The investigated parameters were OT, UAS using, and infection status. The data were analysed by forming two groups according to whether the OT was less than 60 minutes and more, whether the UAS was used and whether an infection occurred. In addition, independent risk factors that may affect postoperative urinary infection development were also investigated by logistic regression analysis. And, a Receiver Operating Characteristic (ROC) curve analysis was applied to determine a cut-off value in OT terms, where infection rates increase more. RESULTS: A total of 575 patients were enrolled in the study. The rates of the usage of UAS and infection were greater statistically in the group for longer than 60 minutes. OT was longer statistically in the infection group than in the group without infection (94.1 ± 14.2 and 68.01 ± 23.1, for groups 1 and 2, respectively, P < .05, Table 2). OT was statistically longer in the UAS group than the unused one (79.3 ± 24.4 and 66.7 ± 22.4, for groups 1 and 2, respectively, P < .05, Table 3). ROC analyses revealed a cut-off point of 87.5 min for OT in terms of infection rate. CONCLUSION: While the infection risk increases when OT exceeds 60 minutes, FURS can be safely performed up to 87.5 minutes with 89% sensitivity and 69% specificity infection risk.

Is laparoscopic adrenalectomy for pheochromocytoma safe and effective in geriatric patients?

OBJECTIVES: The study aimed to assess the haemodynamic changes of laparoscopic adrenalectomy (LA) in geriatric patients with pheochromocytoma (PHEO). To the best of our knowledge, this is the first study to evaluate the haemodynamic outcomes of LA in this patient population. METHODS: Data of 350 patients who underwent single-side transperitoneal LA between 2000 and 2020 were reviewed retrospectively. Patients with a histopathological diagnosis of PHEO were included in the study and classified into two groups according to their ages at the date of surgery. Patients older than 65 years were accepted as elderly according to the World Health Organisation (WHO) recommendations. RESULTS: A total of 54 patients underwent LA for PHEO. Fifteen patients were enrolled in the elderly and 39 in the young groups. There were no significant differences in terms of the operation site (0.564), tumour size (0.878), perioperative results such as mean anaesthesia; operation times, blood loss and haemodynamic changes. There were no significant differences in mean hospitalisation and intensive care unit times. One patient in both groups had grade 1 complication according to Clavien Dindo classification (prolonged ileus, managed with medical treatment and transfusion during surgery, respectively). CONCLUSION: Young and elderly patients had similar outcomes in terms of haemodynamic changes that occurred with LA. LA in elderly patients with PHEO is as safe and effective as in younger patients.

Holmium Laser Enucleation, Laparoscopic Simple Prostatectomy, or Open Prostatectomy: The Role of the Prostate Volume in terms of Operation Time.

INTRODUCTION: To compare the prostate removal speeds of 3 enucleation techniques and to evaluate how the operating times change depending on the prostate volume. METHODS: Medical records of patients with 80-g or larger prostates who underwent holmium laser enucleation of the prostate (HoLEP), laparoscopic simple prostatectomy (LSP), or open prostatectomy (OP) due to medical treatment-resistant benign prostatic hyperplasia (BPH) were reviewed retrospectively. Patients were classified into 3 groups according to the surgical procedure. Age, BMI, prostate weights, total operation times, prostate removal speeds, hospitalization and catheterization days, complications, and improvements on functional outcomes in the 3rd month of follow-up were compared between groups. In addition, the association between prostate weight and total operation time was analyzed for each group. RESULTS: HoLEP, LSP, and OP groups consisted of 60, 61, and 37 patients, respectively. While HoLEP was similar to OP in terms of prostate removal speed and total operation time, LSP was statistically slower and required more operation time than HoLEP and OP. There was a relationship between prostate weight and total operation time only in HoLEP. CONCLUSION: LSP, one of the enucleation techniques in the treatment of large prostates, was slower and required more operation time than HoLEP and OP in terms of total operation time and prostate removal speed. HoLEP seems going to be the fastest candidate for the rapid removal of large prostates in the future.

A Prediction Model of Operation Efficacy Using Protruding Prostate Lobe Volume in Patients Who Are Candidates for Transurethral Resection of Prostate.

PURPOSE: To create a prediction model that could preoperatively measure the success of the transurethral prostate resection (TURP) because of bladder outlet obstruction. METHODS: Patients aged 50-80 years applied with TURP were examined prospectively and evaluated in respect of the preoperative and postoperative values of maximum flow rate (Qmax), international prostate symptom score (IPSS), quality of life (QoL) score and post-voiding residual (PVR) urine amount. On the preoperative transabdominal ultrasonography, total prostate volume (TPV), and protruding prostate lobe volume (PPLV) were measured and the protruding ratio (PR), as the ratio of PPLV to TPV, was calculated. Based on the mean of the preoperative and postoperative Qmax difference (Qmax-D) value, Group 1 (n = 33) was defined as "low efficacy" and Group 2 (n = 30) as "high efficacy". RESULTS: A correlation was determined between the QMax-D, IPSS difference, PVR difference, and QoL difference measured for the efficacy of the operation, and TPV, PPLV and PR. The results of multivariate analysis showed the main effect to be created by PR (p = 0.000; OR 1.596). In the evaluation with receiver operating characteristic curve analysis of high efficacy obtained in the TURP, a significantly powerful effect of the measurements of PPLV area under curve (AUC 0.922 [0.855-0.989] p= 0.000) and PR (AUC 0.954 [0.982-1.000] p = 0.000) was determined. The cutoff value of 11.5 was detected for PR. Efficacy sensitivity and the positive predictive values were recorded as 93.3%, and specificity and negative predictive value as 93.9%. CONCLUSION: When determining candidate patients for TURP surgery, measurements of the PPLV and especially the PR should be taken into consideration in the preoperative prediction of efficacy.

Challenging risk factors for right and left laparoscopic adrenalectomy: A single centre experience with 272 cases.

PURPOSE: This study aimed to compare perioperative and postoperative results of right and left laparoscopic adrenalectomy (LA), and to evaluate the impact of challenging factors on these outcomes. MATERIALS AND METHODS: A total of 272 patient's medical records that underwent single side LA between October 2006 and September 2017 were retrospectively reviewed. The patients were divided into 2 groups according to operation side. Moreover, pheochromocytoma, metastatic masses and adrenal lesions >5cm in size were considered to be difficult adrenalectomy cases and the outcomes of these cases were compared between two groups. RESULTS: 135 patients (49.6%) underwent right LA and 137 patients (50.4%) underwent left LA. Operation time, estimated blood loss (EBL) and hospitalization time were similar between the groups (p=0.415, p=0.242, p=0.741, respectively). Although EBL was higher on the right side than the left (p=0.038) in the fi rst 20 cases, after this learning period has been completed, there was no significant difference between the groups. In patients with pheochromocytoma, metastatic mass and a mass >5cm in size, despite bleeding complications were clinically higher on the right side, this difference was not statistically significant. CONCLUSIONS: During the learning period of LA, EBL is higher on the right side. Due to the greater risk of bleeding complications on the right side even on the hands of experienced surgeons, extra care and preoperative planning are required in patients with pheochromocytoma, metastatic masses and masses >5cm in size.

The role of retrograde intrarenal surgery in kidney stones of upper urinary system anomalies.

INTRODUCTION: Fusion, pelvic, and duplicated urinary tract anomalies of the kidney are rarely seen. There might be some difficulties in the stone treatment, in the administration of extracorporeal shockwave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PCNL), and laparoscopic pyelolithotomy procedures in these patients due to the anatomical variations in kidneys with anomalies. AIM: To evaluate RIRS results on patients with upper urinary tract anomalies. MATERIALS AND METHODS: Data of 35 patients with horseshoe kidney, pelvic ectopic kidney, and double urinary system in two referral centers were reviewed retrospectively. Demographic data, stone characteristics, and postoperative characteristics of the patients were evaluated. RESULTS: The mean age of patients (n=35, 6 women and 29 men) was 50 years. Thirty-nine stones were detected. The total mean stone surface area in all anomaly groups was found to be 140 mm2, and the mean operative time was 54.7±24.7 minutes. The rate of using ureteral access sheath (UAS) was very low (5/35). Eight patients needed auxiliary treatment after the operation. The residual rate, which was 33.3% in the first 15 days, decreased to 22.6% in the third month follow-ups. Four patients had minor complications. In patients with horseshoe kidney and duplicated ureteral systems, it was observed that the risk factor increasing the presence of residual stones was the total stone volume. CONCLUSIONS: RIRS for kidneys with low and medium stone volume anomalies is an effective treatment method with high stone-free and low complication rates.

Should We Hesitate to Perform Laparoscopic Adrenalectomy for Pheochromacytomas Larger Than 5 cm in Diameter with No Pre-Operative Suspicious Criteria for Malignancy?

Objectives: We aimed to compare the outcomes of patients who underwent laparoscopic adrenalectomy (LA) for pheochromacytoma (PHE) ≥5 cm versus <5 cm in diameter. Methods: Demographic variables, tumor characteristics, perioperative, and post-operative outcomes were evaluated retrospectively and compared between groups. Results: Between February 2008 and August 2020, 54 patients (27 female and 27 male) enrolled to the study and divided into two groups according to the tumor size as group L ≥5 cm (28 patients) and group S as <5 cm (26 patients). Groups compared in the aspect of American Society of Anesthesiologists scores, body mass index, tumor locations, ratio of elder (≥60-years-old) patients, and gender ratio were similar between groups S and L (p=0.572, p=0.516, p=0.6, p=0.331, and p=0.207, respectively). Mean duration of surgery (p=0.266), mean estimated blood loss (p=0.587), and mean length of hospital stay (p=0.374) were similar between groups. Difference between maximum and pre-operative systolic pressure and the difference between maximum and pre-operative diastolic pressure were similar between S and L groups (p=0.852 and p=0.526, respectively). Patients whose systolic blood pressure >160 mmHg, systolic blood pressure >30% of baseline, and heart rate >110 (p=0.307, p=0.609, and p=0.296) were similar. Diastolic blood pressure <30%, there is a difference between groups in favor of group L, but not statistically different (p=0.077). Conclusion: It is necessary to work in coordination with endocrinologists and anesthesiologists and LA for PHE should be performed in experienced medical centers regardless of tumor size with multidisciplinary approach.

Monocyte-to-High-Density Lipoprotein Cholesterol Ratio Is Independently Associated With All-Cause Mortality in Deceased Donor Kidney Transplant Recipients.

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.

Laparoscopic ureterolithotomy; an equally effective and a sensible alternative to flexible ureterorenoscopy in the management of large ureteral stones in terms of effectivity and cost.

OBJECTIVES: We aimed to understand whether laparoscopic ureterolithotomy (LU) is a good alternative to flexible ureterorenoscopic lithotripsy (FURS) by comparing these techniques concerning cost-effectiveness. METHODS: We analysed 79 patients with upper ureteral stones larger than 1.5 cm underwent FURS or LU concerning cost-effectiveness analysis. The data including age, body mass index (BMI), stone size, operation time, hospitalisation time, complications and stone-free rates of 15th day and 3rd months. We audited the costs of FURS and LU and compared them concerning cost-effectiveness. RESULTS: There was not any statistically significant difference between the two groups with regard to age, BMI, stone size, stone-free rates at the 3rd month, and complication rates, (p>0.05). The operation times were statistically lower in the FURS than in the LU (61.5±24.3 min and 140.9±49.1 min, respectively, p<0.05). The stone-free rate at the 15th day was lower in the FURS group than in the LU group (31 (81.6%) and 41 (100%), respectively, p<0.05) (Table   I). However, this statistical difference disappears at 3 months (p>0.05). The mean costs of FURS and LU were $194.2±12.4 and $179.2±58.5, respectively (p<0.001). CONCLUSION: FURS is equally effective to LU in terms of stone-free rates. The cost of FURS is higher statistically than LU. FURS is shown as the first choice for the upper ureteral stones larger than 10 mm in size, if the laparoscopic experience is in high-level situations in that clinic, LU may be a suitable alternative to FURS, especially for challenging cases.

OBJETIVOS: El objetivo es determinar si la ureterolitectomia laparoscópica (UL) es una buena alternativa a la ureterorenoscopia flexible con litotricia (URSF) a través de la comparación de ambas técnicas en lo que a coste y efectividad radica.MÉTODOS: Analizamos 79 pacientes con litiasis ureterales proximales de más de 1,5 cm que recibieron URSF o UL en relación a coste-efectividad. Los datos recogidos incluyeron edad, IMC, tamaño de la litiasis, tiempo de la cirugía, tiempo de hospitalización, complicaciones y tasa libres de litiasis a los 15 días y 3 meses de la cirugía. Auditamos los costes de las URSF y UL y se compararon en relación a coste-efectividad. RESULTADOS: No hubo diferencias estadísticamente significativas entre los grupos en relación a la edad, IMC, tamaño de la litiasis, tasa libre de litiasis a los 3 meses y complicaciones (p>0,05). Los tiempos quirúrgicos fueron estadísticamente menores en URSF en comparación a UL (61,5±24,3 min y 140,9±49,1 min, respectivamente, (pz0,05). La tasa libre de litiasis a los 15 días fue mas baja en el grupo de URSF que UL (31 (81,6%) y 41 (100%), respectivamente, p <0,05](Tabla I).Aunque la diferencia estadística desaparece a los 3 meses (p>0,05). El coste medio de URSF y UL fue de $194,2 ± 12,4 y $ 179,2 ± 58,5, respectivamente (pCONCLUSIÓN: URSF es igualmente efectiva que UL en términos de tasa libre de litiasis. Los costes de URSF es más alto que UL. URSF es la primera opción en el tratamiento de litiasis de más de 1 cm en uréter proximal. En caso de experiencia laparoscópica de alto nivel, UL puede sustituir a URSF, especialmente en casos difíciles.

The Differences Between the Right and Left Side Laparoscopic Donor Nephrectomy Outcomes: A Comparative Analysis of Single-Center Outcomes.

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.

Is 6 cm Diameter an Upper Limit for Adrenal Tumors to Perform Laparoscopic Adrenalectomy?

Background: We aimed to compare the results of patients who underwent laparoscopic adrenalectomy (LA) for masses ≥6 cm versus <6 cm in diameter in our tertiary referral university hospital. Materials and Methods: Three hundred thirty consecutive patients were divided into two groups according to tumor size (≥6 and <6 cm in diameter). Demographic variables, body mass index (BMI), lesion localization (right/left), tumor diameter, pathological diagnosis and surgical outcomes, including operation time, estimated blood loss (EBL), conversion to open surgery, complications, and length of hospital stay were compared between groups. Results: Between February 2008 and March 2020, 53 patients (29 male-24 female) with ≥6 cm (L group) adrenal tumor and 277 patients (105 male-172 female) with <6 cm tumor (S group) underwent transperitoneal LA. One hundred sixty-eight (50.9%) tumors localized on the left side. In L group mean tumor size in female and male patients was 87.5 ± 40.8 mm (range 50-225 mm) and 67.3 ± 18.4 mm (range 10-100 mm), respectively (P < .05). Age, American Society of Anesthesiology scores, BMI, and mean operation time were similar between groups (P > .05). Postoperative complications were more often in L group (P = .005). EBL in group L and group S was 86 ± 70.4 mL (range 10-500 mL) and 55 ± 44.2 mL (range 10-300 mL), respectively (P = .003). Length of hospital stay in group L and group S was 3.7 ± 3.5 days (range 1-26) and 3 ± 1.6 days (range 1-9), respectively (P = .086). Significant variables in multivariate analysis, including gender (male), EBL, and postoperative complication rate, were entered into multivariate regression analysis, which presented that EBL and postoperative complication rates were independent significants for the L group. Conclusion: Six centimeters should not be considered as an upper limit of transperitoneal lateral LA and may be safely performed in centers with experience. Further studies are needed to confirm our data.

The Survival of Flexible Ureterorenoscopes in Terms of the Total Stone Area and Total Usage Time.

Introduction: We investigated the survival of a flexible ureterorenoscope (FURS) in regard to the total stone area (TSA) and total usage time (TUT) to determine the cutoff values for its survival. Materials and Methods: Data were obtained from 1326 patients who underwent flexible ureterorenoscopy. The stone area and the usage time of the FURS were obtained in each case. The data from each FURS were considered as a group. The TSA was calculated as the sum of the stones for which only one FURS broke, and the TUT was calculated as the sum of the time of use within the body in all cases during the tool's survival. Data from 13 groups of 1258 patients were analyzed in regard to the TSA and TUT. Results: We found a positive correlation of the case number with the TSA and TUT. The Pearson correlation coefficients were 0.983 and 0.937 for the TSA and TUT, respectively (p < 0.05). The mean case number, TSA, and TUT where only one FURS was used were 97.38 ± 31.34, 11,886 ± 4567.93 mm2, and 5160 ± 1570.52 minutes, respectively. The area under the curve (AUC) of the receiver operating characteristic curve of the FURS survival for the TSA was 91.7% (95% confidence interval [CI]: 0.76-1.07). The best cutoff value for the FURS survival was 6838 mm2, with a sensitivity of 91%. The results for the AUC and the best cutoff value in regard to the TUT for using only one FURS were 66.7% (95% CI: 0.4-0.93) and 4617 minutes, respectively, with a sensitivity of 66%. If the cutoff value is taken as the average value of the TSA and TUT, the sensitivity rate drops to ∼58% and 50%, respectively. Conclusion: FURS can be safely used when the stone area and TUT are about 9158 mm2 and 4617 minutes, respectively, with a sensitivity of 66%.

The effects of laparoscopic urologic surgery on cardiac functions: A pulse wave velocity study.

OBJECTIVE: The aim of this study is to evaluate the effects of laparoscopic urologic surgery on cardiac functions by the parameter pulse wave velocity (PWV), a noninvasive method. MATERIAL AND METHODS: Between July 2012 and February 2013, a total of 47 patients were included in this prospective controlled study. Patients who have been scheduled for laparoscopic surgery (LS) (n=30) and open surgery (n=17) were enrolled in the study. Preoperative, perioperative, and postoperative cardiovascular parameters were measured by a PWV instrument, and the results were compared between laparoscopic (L) group and open (C) group. RESULTS: In the L group, compared to preoperative values, perioperative systolic arterial pressure, diastolic arterial pressure, and mean arterial pressure increased considerably, by 2.6%, 7.9%, and 4.7%, respectively. This was in contrary to reductions in these parameters by 9.5%, 5.7%, and 10%, respectively, in the C group. For the L group, cardiac output (CO) and cardiac index (CI) were increased in the perioperative period and decreased in the postoperative period. For the C group, there were no changes in measurements of perioperative and postoperative CO and CI. However, these changes in CO and CI were not significantly different between the L and C groups. Postoperative large artery elasticity index decreased in both groups. However, these changes did not represent significant difference between groups. CONCLUSION: Compared to open surgery, LS may cause increases in perioperative blood pressures. In addition, increased blood pressures may last even on the first postoperative day. These effects may be more important for patients with high cardiovascular risk.

Laparoscopic Transperitoneal Radical Nephrectomy for Renal Masses with Level I and II Thrombus.

BACKGROUND: We aimed to report surgical and oncological outcomes of renal cell carcinoma (RCC) patients with level I and II thrombus treated with laparoscopic transperitoneal radical nephrectomy. PATIENTS AND METHODS: Medical records of 13 patients were reviewed retrospectively in a single center between 2005 and 2017. Hem-o-lok® clips were used to secure renal artery and renal vein, excluding 2 patients with an attached thrombus on the right side. RESULTS: Seven male and 6 female patients were treated laparoscopically, and conversion to open surgery was not required in any case. The mean age was 61.6 ± 7.8 years (range 45 to 75 years) and the mean body mass index was 27 ± 4.6 kg/m2 (range 18.8 to 34.5 kg/m2). Median tumor size was 9.5 × 7.3 cm (range 5 to 14 cm) and 5 patients who had preoperative metastases underwent cytoreductive nephrectomy. The mean operative time was 137.6 ± 45.8 minutes (range 60 to 200 minutes) and blood loss was 105 ± 34.9 mL (range 50 to 150 mL). The mean hospital stay was 4.4 ± 3.9 days (range 1 to 15 days). Splenic capsular injury occurred in 1 patient and the vena cava was injured in another. Three patients needed blood transfusions. The mean follow-up period was 25 months (range 12 to 86 months). CONCLUSION: Laparoscopic transperitoneal radical nephrectomy can be reliable option for surgical management of RCC with level I and II thrombus in experienced centers.

Comparision of Percutaneous Nephrolithotomy and Retrograde Intrarenal Surgery For The Treatment of Multicalyceal and Multiple Renal Stones.

PURPOSE: Comparison of efficiency and reliability of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in treatment of multicalyceal and multiple renal stones in the same renal unit. MATERIALS AND METHODS: Between 2011 and 2015, records of patients who underwent surgery for renal stone were retrospectively reviewed. Patients who had multiple stones located in different calices in the same renal unit were included. The patients that underwent PNL and RIRS were defined as Group I and Group II, respectively. Patient criteria (age,sex); the stone characteristics; time of procedure, fluoroscopy and hospitalization; stone-free and complication rates of groups were evaluated between the treatment groups. RESULT: There were no significant differences in terms of age, gender, BMI, laterality, number of stones, number of stone localization, hounsfield units and surface area characteristics of the stone between the PNL (n = 47) and RIRS (n = 35) groups (P = .558, P = .278, P = .375, P = 0.051, P = .053, P = .064, P = .642, P = .080, respectively). Stone free rate was 59.6% (n=28) in PNL, and 88.6% (n=31) in RIRS (P=.004). 1st or 2nd degree complications according to Modified Clavien Classification developed in 10 patients (21.3%) in Group I and 1 patient (2.9%) in Group II (P = .015). The 3A or 3B complications were similar in groups (P = .077). Time of procedure, fluoroscopy and hospitalization were significantly lower in Group II (P < .001, P < .001 and P < .001, respectively). CONCLUSION: RIRS is more effective and more reliable procedure than PNL with higher stone-free and lower complication rates in treatment of multicalyceal and multiple stone in the same renal unit.

Penile Plication With or Without Degloving of the Penis Results in Similar Outcomes.

BACKGROUND: Penile plication techniques with or without degloving offer a minimally invasive option for the treatment of penile curvature. AIM: To review the outcomes of penile plication surgery and patient satisfaction with and without degloving of the penis. METHODS: We conducted a retrospective analysis of 52 patients who underwent penile plication for the treatment of Peyronie disease or congenital penile curvature. OUTCOMES: Surgical success rates, complications, and patient satisfaction determined with the Treatment Benefit Scale were compared between groups. RESULTS: The overall surgical success rate was 92.3% at a mean follow-up of 18.84 ± 23.51 months. There were no intraoperative complications. In the degloving group, 42.6% of patients were greatly satisfied and 42.6% had better outcomes; in the without degloving group, 61.5% of patients were greatly satisfied and 30.8% had better outcomes. Comparison of outcomes was not statistically significant between groups. CLINICAL IMPLICATIONS: The results of the present study indicate the two techniques can be used for penile plication. CONCLUSION: With or without degloving, penile plication is safe and effective and provides high patient satisfaction. Kadirov R, Coskun B, Kaygisiz O, et al.

Open vs Laparoscopic Simple Prostatectomy: A Comparison of Initial Outcomes and Cost.

INTRODUCTION: We compared the cost-effectiveness of laparoscopic simple prostatectomy (LSP) vs open prostatectomy (OP). PATIENTS AND METHODS: A total of 73 men treated for benign prostatic hyperplasia were enrolled for OP and LSP in groups 1 and 2, respectively. The findings were recorded perioperative, including operation time (OT), blood lost, transfusion rate, conversion to the open surgery, and the complications according to the Clavien Classification. The postoperative findings, including catheterization and drainage time, the amount of analgesic used, hospitalization time, postoperative complications, international prostate symptom score (IPSS) and International Index of Erectile Function (IIEF) scores, the extracted prostate weight, the uroflowmeter, as well as postvoiding residual (PVR) and quality of life (QoL) score at the postoperative third month, were analyzed. The cost of both techniques was also compared statistically. RESULTS: No statistical differences were found in the preoperative parameters, including age, IPSS and QoL score, maximum flow rate (Qmax), PVR, IIEF score, and prostate volumes, as measured by transabdominal ultrasonography. No statistical differences were established in terms of the OT and the weight of the extracted prostate. No differences were established with regard to complications according to Clavien's classification in groups. However, the bleeding rate was significantly lower in group 2. The drainage, catheterization, and hospitalization times and the amount of analgesics were significantly lower in the second group. The postoperative third month findings were not different statistically. Only the Qmax values were significantly greater in group 2. While there was only a $52 difference between groups with regard to operation cost, this difference was significantly different. CONCLUSION: The use of LSP for the prostates over 80 g is more effective than the OP in terms of OT, bleeding amount, transfusion rates, catheterization time, drain removal time, hospitalization time, consumed analgesic amount, and Qmax values. On the other hand, the mean cost of the LSP is higher than OP. Better effectiveness comes with higher cost.

Unfavorable anatomical factors influencing the success of retrograde intrarenal surgery for lower pole renal calculi.

PURPOSE: To determine the unfavorable factors, related to lower pole anatomical characteristics (LPACs), influencing the success of retrograde intrarenal surgery (RIRS) for lower pole renal calculi (LPC). MATERIALS AND METHODS: We reviewed the data of 36 patients who underwent RIRS for LPC between October 2012 and October 2013. The infundibulopelvic angle (IPA), infundibular length (IL) and infundibular width (IW) were measured on preoperative intravenous urographies. On follow-up stone-free status was defined as complete clearance at the first month kidney-ureter-bladder X-ray and computed tomography if necessary. RESULTS: The median stone size was 10 mm (range, 5-35). The stone-free rates according to LPACs at the first month follow-up were 100% (n = 17), 57.9% (n = 11), 90% (n = 18), 62.5% (n = 10), 90.5% (n = 19) and 60% (n = 9) for patients with IPA ≥ 70°, IPA < 70º, IL < 3 cm, IL ≥ 3 cm, IW ≥ 5 mm and IW < 5 mm, respectively. While IPA and IW were associated with success of RIRS for LPC in multivariate analysis (P = .003 and P = .046, respectively), only IW was found to be a significant factor after applying multivariate analysis (P = .05). CONCLUSION: The results of our study demonstrated that only IW had a significant effect on the success rate of RIRS for LPC.
