Evaluation of the effect of 9.5/11.5-fr ureteral access sheath use on acute kidney injury with the myo-inositol oxygenase biomarker in patients undergoing retrograde intrarenal surgery: a prospective, randomized, and controlled study.

INTRODUCTION: We aimed to investigate whether a low intrarenal pressure provided by ureteral access sheath (UAS) use had a positive effect on the prevention of acute kidney injury through the evaluation of the myo-inositol oxygenase (MIOX). MATERIAL AND METHODS: The patients were divided into two groups according to whether a 9.5/11.5-Fr UAS was used during retrograde intrarenal surgery (RIRS): UAS group and non-UAS group. RIRS was performed under gravity irrigation and manual pumping was not used. For the measurement of MIOX, 5 cc blood samples were taken from the patients preoperatively and four hours postoperatively. RESULTS: Operation time and hospital stay were significantly longer in the UAS group. The mean preoperative and postoperative MIOX values were 0.77 ± 0.36 ng/ml and 0.74 ± 0.38 ng/ml, respectively, in the UAS group, and 0.74 ± 0.31 ng/ml and 0.83 ± 0.40 ng/ml, respectively, in the non-UAS group. The mean MIOX change was -0.29 ± 0.36 in the UAS group and 0.08 ± 0.44 in the non-UAS group, indicating no significant difference between the groups. CONCLUSION: Even if UAS is not used, significant acute kidney injury is not observed under gravity irrigation and therefore, if we avoid manual pumping, the intrarenal pressure remains low, thus potentially rendering the use of 9,5/11,5-Fr UAS unnecessary.

Bladder Stone Formation due to Intravesical Migration of the Intrauterine Device: A Report of 2 Cases.

INTRODUCTION: Approximately 5% of bladder stones occur in women and are usually associated with foreign bodies or urinary stasis. Spontaneous migration of the intrauterine device (IUD) into the bladder is a rare complication. In this report, we present 2 cases of migrated IUD who had undergone surgery at our clinic due to bladder stones. CASE PRESENTATIONS: We detected migrated IUDs into the bladder in 2 female patients, aged 37 and 56 years, who presented with lower urinary tract symptoms and urinary tract infection. In the first case, endoscopic cystolithotripsy was performed, and the IUD was removed without complications. In the second case, the IUD could not be removed endoscopically since it had fractionally invaded the bladder wall, and the IUD was removed without complications by performing an open cystolithotomy. CONCLUSION: A comprehensive gynecological history should be taken from every female patient presenting with recurrent urinary tract infections and lower urinary tract symptoms. If these patients have a history of IUD placement, the possibility of the intravesical migration of this device should be kept in mind.

Prediction of infective complications after retrograde intra renal surgery using Machine learning.

BACKGROUND: To compare the models obtained with classical statistical methods and machine learning (ML) algorithms to predict postoperative infective complications (PICs) after retrograde intrarenal surgery (RIRS). MATERIAL AND METHODS: Patients who underwent RIRS between January 2014 and December 2020 were retrospectively screened. Patients who did not develop PICs were classified as Group 1 and patients who developed as Group 2. RESULTS: Three-hundred and twenty-two patients were included in the study; 279 patients (86.6%) who did not develop PICs were classified as Group 1, and 43 patients (13.3%) who developed PICs were classified as Group 2. In multivariate analysis, the presence of diabetes mellitus, preoperative nephrostomy, and stone density were determined to be factors that significantly predicted the development of PICs. The area under the curve (AUC) of the model obtained by classical Cox regression analysis was 0.785, and the sensitivity and specificity were 74% and 67%, respectively. With the Random Forest, K- Nearest Neighbour, and Logistic Regression methods, the AUC was calculated as 0.956, 0.903, and 0.849, respectively. RF's sensitivity and specificity were calculated as 87% and 92%, respectively. CONCLUSION: With ML, more reliable and predictive models can be created than with classical statistical methods.

Analysis of the Causes of Newborn Priapism: A Retrospective Clinical Study.

Priapism is a rare condition in the newborn. The aim of this study was to investigate the demographic, etiologic and clinical features of neonatal priapism. We retrospectively analysed the data of 11 patients diagnosed with neonatal priapism in the neonatal intensive care unit between 2000 and 2019. Priapism was defined as an erection in the neonatal period, lasting more than 4 hours. Etiological examinations revealed polycythemia in one (9.09%) patient, D-dimer elevation in three patients, and heterozygous methyltetrahydrofolate 667 gene mutations in one patient. Other patients were considered idiopathic. Detumescence was achieved in all 11 (100%) patients during the follow-up period. The median hospitalization duration was 6 (IQR [4, 8]; range, 2-9) days. The median follow-up duration was 38 (IQR [30, 42]; range, 13-94) months for patients followed-up in our hospital after discharge. Neonatal priapism is a rare condition. Successful treatment results can be achieved with conservative methods. Data acquired from our study showed that diseases with a tendency to hypercoagulation belong to the etiology by damaging penile microcirculation and make the response to conservative treatment more challenging.

Can shock wave lithotripsy lead to impaction of ureteral stones?

BACKGROUND: One of the underlying reasons for shock wave lithotripsy (SWL) resistance is the ureteral stone impaction. This study aimed to investigate the accuracy of the hypothesis, suggesting that SWL per se can be the reason for ureteral stone impaction. METHODS: One hundred and seventy-six patients were enrolled in the study. Data of the patients (N.=50) treated with SWL and subsequent semirigid ureteroscopic laser lithotripsy (SULL) in our center between January 2014 and January 2020 were retrospectively reviewed compared with the data of the patients (N.=126) who underwent SULL without prior SWL treatment during the same period. Patients reported to have ureteral stone impaction during SULL were compared with those without stone impaction in terms of demographic parameters, stone characteristics and clinical data, including symptom duration and presence or absence of SWL history. RESULTS: The success rate of SULL was determined as 80.1% (141/176). Univariable analysis revealed statistically significant differences between the patients with and without stone impaction concerning stone diameter, stone volume, pre-SULL SWL history, symptom duration and ureteral wall thickness (UWT). Multivariable logistic regression analysis revealed that symptom duration and UWT were independent predictive factors for ureteral stone impaction. CONCLUSIONS: Symptom duration and UWT are independent predictors of ureteral stone impaction. Symptom duration and UWT should be considered during treatment planning and informed consent process before proceeding with SULL.

Efficacy of combination therapy with biofeedback and dapoxetine in lifelong premature ejaculation treatment: a prospective randomized study.

PURPOSE: Premature ejaculation (PE) is a common sexual dysfunction that significantly affects the quality of life of the patient and their partner. We aimed to compare the efficacy and safety of the combination therapy with biofeedback-guided pelvic floor exercise therapy (BFT) and dapoxetine 30 mg. METHODS: Sixty-five patients diagnosed with lifelong PE were included in the study. Patients were divided into three groups as BFT, dapoxetine 30 mg and a combination of BFT and dapoxetine 30 mg. The patients were compared with the intravaginal ejaculatory latency time (IELT) pre-treatment and post-treatment 1st and 3rd months. RESULTS: The mean IELTs of the patients in Group 1 were 40 s in pre-treatment, 115 s at the end of the 4th week and 140 s at the end of the 12th week. The IELT values of the patients in Group 2 were 40 s in pre-treatment, 145 s in the 4th week and 170 s in the 12th week. The IELT values were calculated in Group 3 as 42.5 s in pre-treatment, 185 s in the 4th week and 205 s in the 12th week When the IELT was statistically compared between the groups at 1st and 3rd months, the duration in the combination group was found to increase significantly (p < 0.001). CONCLUSION: Combination therapy with BFT and dapoxetine 30 mg in lifelong PE treatment is a good alternative with a low side effect profile and acceptable continuous efficiency.

Is biofeedback-assisted pelvic floor muscle training superior to pelvic floor muscle training alone in the treatment of dysfunctional voiding in women? A prospective randomized study

ABSTRACT Purpose: To compare the effectiveness of biofeedback-assisted pelvic floor muscle training (PFMT) and PFMT alone on voiding parameters in women with dysfunctional voiding (DV). Materials and Methods: The patients in group 1 (34 patients) were treated with biofeedback-assisted PFMT, and the patients in group 2 (34 patients) were treated with PFMT alone for 12 weeks. The 24-hour frequency, average voided volume, maximum urine flow rate (Qmax), average urine flow rate (Qave), post-void residual urine volume (PVR), and the validated Turkish Urogenital Distress Inventory (UDI-6) symptom scores were recorded before and after 12 weeks of treatment. Results: At the end of treatment sessions, the Qmax and Qave values of the patients in group 1 were significantly higher than those in group 2, and the PVR in the patients in group 1 was significantly lower than those in group 2 (p=.026, .043, and .023, respectively). The average UDI-6 symptom scores of the patients in group 1 were significantly lower than those in group 2 (p=.034). Electromyography activity during voiding, in group 1 was significantly lower than in group 2 (41.2 vs. 64.7, respectively, p=.009). Conclusion: Biofeedback-assisted PFMT is more effective than PFMT alone in improving clinical symptoms, uroflowmetry parameters, and EMG activity during voiding.

The role of penile elastography in the evaluation of erectile dysfunction in patients with chronic obstructive pulmonary disease.

Introduction: In this study, we aimed to measure the change in penile stiffness by evaluating corpus cavernosum (CC) with shear wave elastography (SWE) in patients with chronic obstructive pulmonary disease (COPD). Material and methods: Seventy outpatient patients aged 50-80 years who were diagnosed with COPD were evaluated using SWE. Patients were divided into 2 groups according to the International Index of Erectile Function-5 (IIEF-5) questionnaire (IIEF-5 >17: Group A, IIEF-5 <17: Group B). The measurements were made in both transverse and longitudinal sections. Results: The mean age of the patients was 60 ±7.9 years. The duration of COPD was significantly higher in Group B than in Group A (p = 0.003). The mean SWE values of right transverse mid-portion of corpus penis (RTM) and left transverse mid-portion of corpus penis (LTM) in Group B (21.1 ±5.6 kPa and 20.8 ±4.8 kPa, respectively) were significantly higher than in Group A (15.2 ±2.3 kPa and 15.8 ±2.7 kPa, respectively); (p <0.001 and p <0.001, respectively). There was a significant negative correlation between IIEF-5 scores and the duration of COPD (p <0.05). There was a significant negative correlation between IIEF values and RTM and LTM values of the patients (p <0.05 and p <0.05, respectively). There was a significant positive correlation between the duration of COPD and both RTM and LTM values (p <0.05 and p <0.05, respectively). Conclusions: In our study, according to the SWE findings, we showed the effect of systemic changes created by COPD on penile tissue and the negative effect of this on erectile function in patients.

Desires and attitudes of outpatients and physicians regarding the use of teleurology during the pandemic: a prospective survey study.

OBJECTIVE: It is not known to date how many patients admitted to urology outpatient clinics are willing to use telemedicine. We aimed to investigate knowledge levels and attitudes concerning the utilization of teleurology by patients applying to urology outpatient clinics. METHODS: This prospective multicentre survey study included 334 patients aged 18-65 years who applied to an urology outpatient clinics. The patients were asked questions about their attitudes and expectations regarding teleurology. Diseases were divided into seven subgroups due to the broad spectrum of diagnoses. Physicians' and patients' opinions on whether it was possible to manage the current medical condition via teleurology were recorded. RESULTS: 69.5% of patients stated that they had sufficient technical skills to use teleurology by themselves for medical examination. 55.4% of patients and 78.4% of physicians responded that the existing complaints were suitable for teleurology. Both patients and physicians deemed genital system diseases and urinary tract infections suitable for teleurology (p<0.001, p<0.001 for physicians, and p<0.001, p<0.001 for patients), whereas urine transport, storage and emptying disorders (p=0.003) and benign prostatic hyperplasia (p=0.029) were deemed to be suitable for teleurology only by the physicians. CONCLUSION: Our study shows that (i) the majority of our patient population has a telecommunications infrastructure suitable for teleurology, (ii) teleurology has aroused interest among patients, particularly during the pandemic period, and (iii) physicians and patients have high expectations that the problem can be solved with teleurology in suitable patients.

Comparison of Perioperative, Oncological, and Functional Outcomes of Three-Dimensional Versus Robot-Assisted Laparoscopic Radical Prostatectomy: A Preliminary Study.

Background: Radical prostatectomy (RP) is the first-line treatment modality for prostate cancer and can be performed using retropubic or minimally invasive techniques. New technologies such as the da Vinci robotic system and three-dimensional (3D) laparoscopic imaging system have been developed to overcome the challenges of conventional laparoscopy. This study aimed to compare the perioperative, oncological, and functional outcomes of robot-assisted laparoscopic RP (RALP) and 3D laparoscopic RP (3D LRP). Materials and Methods: The study was approved by the local ethics committee and included 65 patients (38 RALP, 27 3D LRP) who underwent RP with the diagnosis of localized prostate cancer between May 2019 and January 2020. All demographic, clinical, perioperative, pathological, and postoperative variables were recorded. Results: There was no statistically significant difference between the two groups in terms of preoperative patient characteristics. The mean operative times of the RALP and 3D LRP groups were 135.74 ± 11.51 and 165.37 ± 15.86 minutes, respectively, with a statistically significant difference between the two groups (P = .001). The mean estimated blood loss was 237 ± 71 mL in the RALP group and 257 ± 54 mL in the 3D LRP group, with no statistically significant difference between the two groups (P = .236). In the 6 months of follow-up, there was no statistically significant difference between the two groups in terms of biochemical recurrence, continence, and potency. Conclusion: RALP and 3D LRP have similar perioperative, short-term oncological and functional outcomes other than the operative time. There is a need for prospective, randomized studies with larger populations evaluating long-term oncological and functional outcomes.

Robotic perineal radical prostatectomy in a patient with a pre-existing three piece inflatable penile prosthesis.

Radical prostatectomy (RP) is the primary and standard treatment for localized prostate cancer. As in many surgical procedures, RP can now be accomplished through minimally invasive methods. RP in a patient with a pre-existing 3-piece inflatable penile prosthesis (IPP) is an exceptional condition and involves coping with many difficulties. In this case report, we aimed to present a patient with pre-existing 3-piece IPP for whom we successfully performed robotic perineal RP (r-PRP).

Variation of Serum PSA Levels in COVID-19 Infected Male Patients with Benign Prostatic Hyperplasia (BPH): A Prospective Cohort Studys.

OBJECTIVE: To investigate the effect of SARS CoV-2 on serum total PSA levels in men with BPH diagnosed with COVID-19. METHODS: The PSA (Kit: Immunoassay Program- Cycle 18, Siemens Atellica IM Analyzer) levels in patients who had had a PSA check at least 3 months, but no more than 6 months, prior to diagnosis of acute COVID-19 infection, were examined retrospectively. PSA levels were measured and recorded from these patients on the first day of diagnosis of COVID-19. These patients were called back for urology outpatient follow-up at the third month after the end of the COVID-19 treatment. PSA levels measured in the pre-COVID-19 period, during the period of active infection with COVID-19, and in the post-COVID-19 period were compared. RESULTS: In total, 91 patients had a serum PSA level of 1.58 ± 1.09 ng/mL in the pre-COVID-19 period, a serum PSA level of 4.34 ± 3.78 ng/mL measured in the COVID-19 period and 2.09 ± 2.70 ng/mL in the post-COVID-19 period. It was determined that the serum PSA level measured during active COVID-19 infection was statistically significantly higher than the PSA levels measured according to the pre-COVID-19 period and the post-COVID-19 period (P < .001, P < .001; respectively). CONCLUSION: SARS-CoV-2 infection in men diagnosed with BPH causes significant increases in PSA levels during the active period of the disease. Measurement of PSA values used in the diagnosis, differential diagnosis, and follow-up of prostate diseases in the acute period of infection and in the early period after infection treatment may cause false evaluations that may affect the diagnosis and treatment steps of prostate diseases in these patients.

The relationship of serum testosterone levels with the clinical course and prognosis of COVID-19 disease in male patients: A prospective study.

BACKGROUND: A potential role of testosterone among sex hormones has been hypothesized in identifying sex-related differences in the clinical consequences of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Due to the high global prevalence of hypogonadism, the relationship between hypogonadism and SARS-CoV-2 infection outcomes deserves an in-depth study. OBJECTIVE: The present study aimed to investigate the relationship of serum testosterone with other laboratory parameters on the prognosis of coronavirus disease-19 (COVID-19) in male patients with COVID-19 diagnosis. MATERIALS AND METHODS: This prospective cohort study included 358 male patients diagnosed with COVID-19 and 92 COVID-19 negative patients admitted to the urology outpatient clinics as a control group. The COVID-19 patients were divided into groups according to prognosis (mild-moderate and severe group), lung involvement in chest computed tomography (<50% and >50%), intensive care unit needs, and survival. RESULTS: The measured serum total testosterone level of the COVID-19 patients group was found to be significantly lower than that of the control group (median, 140 ng/dl; range, 0.21-328, 322 ng/dl; range, median, 125-674, p < 0.001, respectively). The serum TT levels were statistically significantly lower in severe COVID-19 patients compared to mild-moderate COVID-19 patients (median, 85.1 ng/dl; range, 0.21-532, median, 315 ng/dl; range, 0.88-486, p < 0.001, respectively), in COVID-19 patients in need of intensive care compared to COVID-19 patients who did not need intensive care (median, 64.0 ng/dl; range, 0.21-337, median, 286 ng/dl; range, 0.88-532 p < 0.001, respectively), and in COVID-19 patients who died compared to survivors (median, 82.9 ng/dl; range, 2.63-165, median, 166 ng/dl; range, 0.21-532, p < 0.001, respectively). DISCUSSION AND CONCLUSION: Our data are compatible with low TT levels playing a role on the pathogenesis of the disease in Covid-19 patients with poor prognosis and a mortal course and may guide clinicians in determining the clinical course of the disease.

Factors predicting duration and success of semirigid ureteroscopy for ureteral stones in different localizations. / Factores predictores de la duración y éxito de la ureteroscopia semirígida para litiasis ureterales en diferentes localizaciones.

OBJECTIVE: In this study, we aimed to determine the factors predicting the duration and successof semirigid ureteroscopy performed for the treatment of ureteral stones in different localizations. MATERIALS AND METHODS: Medical records of the patients whom under went semirigid ureteroscopy for urolithiasis in our centre between January 2015 and December 2019 were retrospectively reviewed. The study group composed of 170 patients and divided into three subgroups; of which 54 in proximal ureter (31.8%), 51 in the mid (30 %) and 65 (38.2%) in the distal ureter. Predictive factors of semirigid ureteroscopy duration and success were determined by performance of correlation analysis and multivariate analysis. RESULTS: Overall stone-free rate was calculated as 78.8%. Success rates for proximal, mid and distal ureteral stones were 72.2% (39/54 patients), 74.5% (38/51 patients) and 87.7% (57/65 patients), respectively. Complications were present in 19 patients (11.2%). Multivariate analysis indicated that stone diameter and stone burden independently affected the stone-free rate. Statistically significant negative correlation was determined between success of the procedure and stone diameter, stone burden, impaction and more proximal stone localization. While there was a statistically significant positive correlation between duration of procedure and stone burden, diameter, impaction, historyof ipsilateral ureteroscopy and more proximal stone localization, there was negative correlation between duration of procedure and stone-free status. CONCLUSION: We conclude that stone diameter, stone burden, impaction and more proximal stone localization are common factors affecting both duration and success of semirigid ureteroscopy. In addition, stone size and stone burden were determined as independent markers of stone-free status.

Female Urethroplasty With Dorsal Onlay Labia Minora Graft: Technical Details and Initial Results.

OBJECTIVE: The objective of this study was to evaluate the functional results of dorsal onlay labia minora graft urethroplasty in the treatment of female urethral strictures. MATERIALS AND METHODS: Data were retrospectively examined for 13 patients who underwent augmentation urethroplasty through the dorsal approach using labia minora grafts between September 2017 and January 2019. Demographic, intraoperative, and postoperative data and follow-up conditions were recorded for all patients. RESULTS: The mean age of the patients was calculated as 48.2±7 years. The etiology of urethral strictures was found to be trauma in 2 patients, iatrogenic in 4 patients, and idiopathic causes in 7 patients. The mean urethral stricture length of the patients was 1.5±0.4 cm (range, 1-2.5 cm). The mean surgical duration was 95±11.4 minutes (range, 70-110 minutes). The mean postoperative American Urology Association symptom score, maximum urine flow rate, and postmictional residue values were statistically significantly different compared with preoperative data (P < 0.05). No peroperative and postoperative complications were detected in any patients. The mean follow-up duration of the patients was 19±5.3 months, and no recurrence of stricture was observed in any patients based on the cystourethroscopic examinations. All patients are being followed up in our clinic without any stricture recurrence or symptoms. CONCLUSIONS: The dorsal onlay labia minora graft urethroplasty technique in female urethral strictures is an efficient and applicable method with postoperative anatomic and functional results. Studies with longer follow-up periods and larger patient populations are required to present the success and reliability of this technique.

Surgical results in penile fracture: Our single center experience.

INTRODUCTION: Penile fracture arises as a result of a unilateral or bilateral rupture of the tunica albuginea of the corpus cavernosum. It is a rare condition that requires urgent surgical intervention. In this study, we aimed to determine the effectiveness of surgical treatment in penile fracture and its effect on complications. METHODS: The data of 21 patients who were admitted to the emergency department of our clinic between 2012 and 2019 and underwent emergency surgical repair with the diagnosis of penile fracture were collected retrospectively. The diagnosis of penile fracture was established by anamnesis and physical examination. Age, etiology, duration from trauma to surgery, physical examination findings,length and localization of the tunica albuginea defect, length of hospital stay, and postoperative first-, third- and sixth-month follow-up results were analyzed. Erectile function was evaluated using the International Index of Erectile Function (IIEF-5). Complications such as penile curvature, penile nodule and painful erection were evaluated. RESULTS: The mean age of the patients was 36.8 ± 8.3 years. The most common reason of penile fracture was manually bending the penis for detumescence. All patients underwent surgery. The mean duration from trauma to surgery was 7.6 ± 3.1 h. The mean length of the tunica albuginea defect was 11 ± 2.5 mm. The mean length of hospital stay was 2.5 ± 0.5 days. The mean IIEF-5 scores in the postoperative first, third and sixth months were 20.5 ± 2.6, 22 ± 2.2, 22.1 ± 1.7, respectively. CONCLUSION: Penile fracture is a urological emergency, and timely surgery is an effective treatment method for preventing postoperative complications.
