ABSTRACT

Varicocele is abnormal tortuosity and dilatation of the pampiniform plexus veins within the spermatic cord. Varicocele is associated with testicular atrophy, hypogonadism, impaired semen analysis values, or decreased testosterone production. Varicocele is a progressive disease and should be treated because it may be a systemic disease that can be associated with cardiovascular abnormalities. We hypothesize in this study that cardiovascular and hemodynamic pathologies may occur in varicocele patients. In this prospective, multicentric, multidisciplinary study, patients diagnosed with high-grade left varicocele in the urology clinic underwent semen analysis, total testosterone determination, and scrotal Doppler ultrasonography. In addition, blood pressure measurement and echocardiographic evaluation were performed by blinded cardiologists in both the varicocele patients and the healthy control group. The study was carried out with 103 varicocele patients and 133 healthy individuals who formed the control group. Diastolic blood pressure (P = 0.016), left ventricular end diastolic (P < 0.001) and systolic diameter (P < 0.001), ejection fraction (P < 0.001), pulmonary arterial pressure (P < 0.001), and aortic distensibility (P < 0.001) values were significantly higher in varicocele patients compared with controls; interventricular septum wall thickness (P = 0.022), aortic systolic (P < 0.001) and diastolic diameter (P < 0.001), aortic systolic (P < 0.001) and diastolic diameter index (P < 0.001), and aortic stiffness index (P < 0.001) values were significantly lower in varicocele patients. The mean aortic distensibility of non-normozoospermic group was lower than that of normozoospermic group (P = 0.041). There was no statistically significant relationship between thickest vein diameter in spermatic cord and cardiological parameters. This study showed that symptomatic patients with high-grade varicocele had a higher risk of cardiovascular and hemodynamic disease. We recommend that men with high-grade symptomatic varicocele with impaired semen analysis undergo cardiovascular and hemodynamic evaluation regardless of their spermatic vein diameter.

ABSTRACT

Background and objective: We investigated the ability of preoperative serum values of red blood cell distribution width (RDW), neutrophil lymphocyte ratio (NLR) and plateletcrit (PCT) to predict Fuhrman grades (FG) and tumor stages of renal cell carcinoma in patients who underwent radical nephrectomy. Materials and methods: Records of 283 patients that underwent radical or partial nephrectomy of renal masses at our clinic between January 2010 and April 2018, whose pathology results indicated renal cell carcinoma (RCC), and who had their FG and T1-4 N0M0 identified were retrospectively evaluated. The patients were divided into two groups based on their FG as low (I-II) and high (III-IV) and their T stages were similarly grouped as limited to kidney (pT1-pT2) and not limited to kidney (pT3-pT4). Results: Mean RDW, NLR, PCT cut-off values of the patients for FG and T stage were 15.65%, 3.54, 0.28% and 14.35%, 2.69, 0.28%, respectively. The RDW and NLR were determined to be statistically significant predictors of a pathologically high FG, whereas the PCT value was not a statistically significant predictor of high FG (p = 0.003, p = 0.006, p = 0.075, respectively). The relationship of RDW, NLR and PCT values with a limited to the kidney pathological T stage revealed statistically significant correlations for all three values. Conclusions: We determined that only RDW and NLR were markers predicting FG, while PCT had no prognostic value. On the other hand, all three of these values were associated with a limited to the kidney pathological T stage in patients who underwent nephrectomy due to renal masses and whose pathologies suggested RCC.

ABSTRACT

Aim This study aims to evaluate the results of patients we treated with nephrectomy due to Xanthogranulomatous pyelonephritis (XGP) and the effects of kidney volume on the results. Patients and methods Records of 22 patients who underwent nephrectomy due to renal masses at our clinic between January 2008 and May 2018 and whose pathology results indicated XGP were retrospectively evaluated. The computed tomography (CT) measurement of the kidney volumes of the patients was calculated as the product of the longest length, width, and height of the kidney. The mean kidney volume of the patients was calculated and the patients were distributed into two groups: those that presented volumes below average (Group 1) and above average (Group 2). The patients' mean ages, operative duration, hospitalization days, differences in pre- and postoperative hemoglobin and creatinine levels, and postoperative complications were compared across groups. Results Group 1 consisted of 12 patients and Group 2 of 10 patients. The mean kidney volume of the patients was calculated as 33.4 cm3 ± 26.0 cm3. The mean kidney volume of the patients was 15.8 cm3± 9.9 cm3 in Group 1 and 56.8 cm3 ± 21.8 cm3 in Group 2. There were no statistical differences between the two groups in terms of operative times, preop-postop hemoglobin (Hgb) levels and complications. Conclusion In cases where XGP is considered probable, the priority in preoperative CT must be to thoroughly evaluate the relationship of the kidney with the surrounding tissue and organs rather than to investigate the patients' kidney volumes.

ABSTRACT

OBJECTIVE: To evaluate the effects of previous unsuccessful extracorporeal shockwave lithotripsy (ESWL) treatment on the performance and outcome of percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: Of 1625 PCNL procedures performed in our clinic, 393 renal units with similar stone burden and number of accesses was included in the present study. We categorised the study patients into two groups according to whether they underwent ESWL within 1 year prior to PCNL or not. Accordingly, Group 1 comprised 143 (36.3%) ESWL-treated patients and Group 2 comprised 250 (63.7%) non-ESWL-treated patients. RESULTS: Residual stones were detected in 36 (25.1%) of the ESWL-treated patients (Group 1) and in 60 (24%) of non-ESWL-treated patients (Group 2). There were no statistically significant differences between the groups for length of hospital stay (LOS), nephrostomy tube removal time, and the presence of residual stones. When we evaluated the groups for both the preoperative and postoperative haemoglobin (Hb) drop and blood transfusion rate, manifest Hb declines and more transfusions were required in the ESWL-treated patients (both P = 0.01). CONCLUSIONS: In our study, previous ESWL treatment had no influence on the PCNL stone-free rate, operation time, incidence of postoperative complications, and LOS, in patients with similar stone burdens. However, bleeding during PCNL was more prevalent in the ESWL-treated patients, so close attention should be paid to bleeding in patients who have been pretreated with ESWL.

ABSTRACT

BACKGROUND: Prostate cancer is the most common solid tumor. The incidence of prostate cancer shows regional and racial differences. The ideal PSA threshold for prostate biopsy is still being debated. OBJECTIVE: We aimed to investigate cancer detection rates in Turkish men who underwent transrectal ultrasound-guided prostate biopsy (TRUSPB) who had prostate-specific antigen (PSA) levels in the range of 2.5 to 4.0 ng/mL and compare them with the rates of cancer in patients with PSA levels in the range of 4.0 to 10.0 ng/mL. METHODS: All Turkish men who underwent TRUSPB in our clinic between January 2012 and May 2014 were included; that is, 101 patients (Group 1) with PSA level in the range of 2.5 to 4.0 ng/mL and 522 patients (Group 2) with PSA level in the range of 4.0 to 10.0 ng/mL. Mean PSA level, age, prostate volume, and cancer detection rates were evaluated. RESULTS: The mean age was 60.5 and 64 years in Group 1 and Group 2, respectively (P = 0.06). The mean PSA level was determined as 3.1 and 6.8 ng/mL in Group 1 and Group 2, respectively (P = 0.03). The cancer detection rate was 12.7% in Group 1 (n = 13) and 30.8% in Group 2 (n = 161), which revealed a statistically significant difference between the 2 groups (P = 0.001). In Group 1, 9 of 13 patients (69%) had Gleason score of 6, 3 (23%) had Gleason score of 7, and 1 (8%) had a Gleason score of 8. CONCLUSIONS: The cancer detection rate is lower in Turkish men with PSA level in the range of 2.5 to 4.0 ng/mL when compared with men with PSA level in the range of 4.0 to 10.0 ng/mL. Furthermore, most patients in whom cancer was detected who have a PSA level in the range of 2.5 to 4.0 ng/mL are low risk. Therefore, the benefit of TRUSBP in Turkish men with PSA level between 2.5 and 4 ng/mL is low.

ABSTRACT

OBJECTIVE: To examine the outcomes of the patients who underwent percutaneous nephrolithotomy with single-step dilatation technique in our clinic. MATERIALS AND METHODS: A total of 932 patients who underwent percutaneous nephrolithotomy by using single-step dilation technique in the period between 2008 and 2015 in our clinic were included in the study. Data of the patients were analyzed, such as age, sex, stone burden, operative time, fluoroscopy time, operation success, and perioperative and postoperative complications. RESULTS: An analysis of the data of 932 patients revealed similar operation success and complication rates as in the literature. Mean age of the patients included in the study was 48.9 years. Mean operative time was 66.6 minutes and mean fluoroscopy time was 139 seconds. Postoperative residual stone was detected in 17.1% of the patients. Postoperative fever was observed in 29 patients (3.1%), and sepsis developed in 11 (1.1%) of them. Additional postoperative procedures were required in 29 patients (3.1%). No patient was lost due to complications. Our data were compatible with the literature. CONCLUSION: Single-step dilation technique can be used as an effective and safe alternative dilation method in adult patients.

ABSTRACT

INTRODUCTION: Most of the bladder cancers are tumors without muscle invasion at the time of diagnosis. Transurethral resection is the standard treatment in bladder tumors without muscle invasion. Proper review of transurethral resection is important for correct risk classification. In this study, our main objective was to show that a "second look" in patients with multiple and/or > 3 cm tumors regardless of T stage during the early term can be helpful in detection of possible residues and determining risk classification. MATERIALS AND METHODS: 156 patients with primary, multiple and/or > 3 cm tumors were included in the study. Patients were divided into 3 groups as Group 1 (Ta), Group 2 (T1 without second TUR) and Group 3 (T1 with second TUR). Macroscopic tumor occurrence rates were compared in their 3rd month control cystoscopy. RESULTS: Macroscopic tumor detection rates in patients' 3rd month control cystoscopy were 21 (46.7%) in Group 1, 18 (30%) in Group 2 and 4 (7.8%) in Group 3. When compared with Group 3 patients, Group 1 and Group 2 had higher statistically significant macroscopic tumor detection rates (p = 0.001) CONCLUSION: A second look in patients with multiple and/or > 3 cm tumors during early term will enable the surgeons to detect possible tumors and do a better job in risk classification.

ABSTRACT

INTRODUCTION: This study aimed to evaluate whether one-shot dilatation technique is as safe in patients with a history of open-stone surgery as it is in patients without previous open-stone surgery. METHODS: Between January 2007 and February 2015, 82 patients who underwent percutaneous nephrolithotomy (PNL) surgery with one-shot dilation technique who previously had open-stone surgery were retrospectively reviewed and evaluated (Group 1). Another 82 patients were selected randomly among patients who had PNL with one-shot dilation technique, but with no history of open renal surgery (Group 2). Age, gender, type of kidney stone, duration of surgery, radiation exposure time, and whether or not there was any bleeding requiring perioperative and postoperative transfusion were noted for each patient. RESULTS: The stone-free rates, operation and fluoroscopy time, and peroperative and postoperative complication rates were similar in both groups (p>0.05). CONCLUSIONS: Our experience indicated that PNL with one-shot dilation technique is a reliable method in patients with a history of open-stone surgery.

ABSTRACT

In renal transplantation surgery, double J stents (DJS) are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmentation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery.

ABSTRACT

INTRODUCTION: Radical prostatectomy (RP) is considered the best treatment for the management of localized prostate cancer in patients with life expectancy over 10 years. However, a complete recovery is not guaranteed for all patients who received/underwent RP treatment. Biochemical recurrence is frequently observed during the post-operative follow-up period. The main objective in this study is to evaluate the predictive factors of biochemical recurrence in localized prostate cancer patients who underwent RP surgery. MATERIAL AND METHODS: The study included 352 patients with prostate cancer treated by RP at a single institution between February 2004 and June 2014. Detailed pathological and follow-up data of all patients were obtained and analyzed to determine the results. RESULTS: Mean follow-up duration was 39.7 months. 83 patients (23%) experienced biochemical recurrence (BCR) during the follow-up period. Mean BCR duration range was 6.56 (1-41) months. In multivariate logistic regression analysis, Gleason score (GS), PSA and extra-capsular tumour spread (ECS) variables were found to be statistically significant as BCR predictive factors. CONCLUSIONS: According to our study results, it is thought that PSA, GS and ECS can all be used for guidance in choosing a treatment modality for post-RP biochemical recurrence and metastatic disease as predictive factors. However, there is no consensus in this matter and it is still debated.
