Effect of different alpha-receptor antagonists on metabolic parameters: a head-to-head comparison

PURPOSE

Although it is known that alpha-adrenergic receptor antagonists have positive effects on metabolic parameters such as glucose metabolism, lipid profile, and insulin sensitivity, it is unclear whether this is a class effect. Tamsulosin is reported to have adverse effects on glucose metabolism and insulin resistance, and this may be because of its lack of glycolysis-enhancing effect compared with other alpha-adrenergic receptor antagonists with glycolysis-enhancing effects such as doxazosin, terazosin, and alfuzosin. The aim of this study was to compare the effect of tamsulosin on metabolic parameters with another alpha-1 adrenergic receptor antagonist, doxazosin.

METHODS

In this prospective, observational, controlled, 12-week clinical study, a total of 60 male patients aged ≥ 40 years who were first started on tamsulosin (n = 30; 0.4 mg/day, oral; mean age, 59.20 ± 8.97 years) or doxazosin (n = 30; 4 or 8 mg/day, oral; mean age, 58.50 ± 8.93 years) for benign prostatic hyperplasia (BPH) or lower urinary tract symptoms (LUTS) were enrolled. The groups were compared according to the changes in anthropometric and biochemical parameters (glycemia, lipid profile, and insulin sensitivity) at the end of treatment.

RESULTS

In intragroup analyses, systolic blood pressure, diastolic blood pressure, total cholesterol, and HbA1c levels decreased significantly in the doxazosin group compared with baseline (p < 0.05 for all), while no significant change was observed in the tamsulosin group. In comparisons between groups, systolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol levels showed a significant decrease in the doxazosin group compared with the tamsulosin group (percent change: - 6.68 ± 13.08 vs. 0.53 ± 11.02, p = 0.025; - 3.63 ± 9.56 vs. 4.02 ± 10.86, p = 0.005; and - 5.62 ± 18.18 vs. 5.24 ± 15.42, p = 0.015, respectively).

CONCLUSION

Although these results do not support previous findings that tamsulosin has adverse effects on metabolic parameters, they suggest that doxazosin treatment may be a reason for preference in patients with BPH or LUTS accompanied by metabolic disorder.

Management of Priapism: Results of a Nationwide Survey and Comparison with International Guidelines

OBJECTIVE

The aim of this study is to evaluate current urologic practice regarding the management of priapism in Turkey and compare with international guidelines.

METHODS

Urologists and urology residents were invited to an online survey consisting of 30 multiple-choice questions on priapism-related clinical practices that were consid- ered most important and relevant to practices by using Google Forms.

RESULTS

Total number of responses was 340. Respondents reported that they recorded a detailed patient's medical history and physical examination findings (n = 340, 100%) and laboratory testing, which includes corporal blood gas analysis (n=323, 95%). Participants announced that they performed Doppler ultrasound for 1/4 cases (n = 106, 31%), but 22% of the participants (n=75) replied that they performed in >75% of cases. Participants (n=311, 91%) responded that the first-line treatment of ischemic priapism is decompression of the corpus cavernosum. Moreover, most respondents (n = 320, 94%) stated that sympathomimetic injection drugs should be applied as the second step. About three-quarters of respondents (n = 247, 73%) indicated adrenaline as their drug of choice. Phosphodiesterase type 5 inhibitors seems to be the most pre- ferred drug for stuttering priapism (n=141, 41%). Participants (n=284, 84%) replied that corpora-glanular shunts should be preferred as the first. A large number of par- ticipants (n = 239, 70%) declared that magnetic resonance imaging can be performed in cases with delayed (>24 hours) priapism to diagnose corporal necrosis. Most of the participants (84%) responded that penile prosthesis should be preferred to shunts in cases with delayed (>48 hours) priapism.

CONCLUSION

It would be appropriate to improve the training offered by professional associations and to give more training time to the management of priapism during residency.

What is the best anesthesia method for circumcision? Comparison of local and general anesthesia: Prospective clinical study

Objective: It was aimed to compare the methods of local anesthesia and general anesthesia with circumcision study questionnaire applied before and after circumcision. Material and Methods: Parents of children aged 0-12 years who applied for circumcision between June and December 2021 who agreed to participate in the study were asked to fill out the circumcision study questionnaire. All patients were operated with same surgeon and surgical method. Patients were divided into local and general anesthesia groups, and data were compared. Results: Our study included 282 patients; general anesthesia was applied to 132 patients (48.9%), and local anesthesia was applied to 144 patients (51.1%). Age and weight averages of patients who were administered local anesthesia and age preferences suitable for circumcision were significantly lower than those in general anesthesia group (p:0.001). There was no significant difference between socioeconomic levels, educational status and reasons for circumcision in both groups (p≥0.05). Patients’ need for postoperative care and recovery time was significantly lower in the local anesthesia group (p:0.001). Conclusion: Circumcision is a surgical operation that can be performed safely with local or general anesthesia. Parents who want circumcision in the early months of life mostly prefer local anesthesia. Postoperative recovery time is shorter in this group. Preference for anesthesia has changed in favor of general anesthesia in advanced ages, including the sexual development period. The knowledge and awareness level of our society about circumcision has increased compared to previous years. Keywords: circumcision, local anesthesia, general anesthesia, urinary tract infection

Ultrapreservation in Robotic Assisted Radical Prostatectomy Provides Early Continence Recovery

Background and Objectives

We aimed to evaluate oncological and functional results of the ultrapreservation anterior-sparing technique in patients with localized prostate cancer.

Methods

In this single-center study, patients with low to intermediate risk prostate cancer, who were treated with the ultrapreservation anterior-sparing technique, were included retrospectively. The oncological and functional outcomes were recorded. After the functional and pathological evaluation in the first month, patients' prostate-specific antigen levels were followed, as well as continence and potency status bimonthly for one year. Continence is defined as no leakage and zero pads for security. Patients' potency was evaluated using the Sexual Health Inventory for Men, with ≥ 17 considered potent.

Results

A total of 118 patients were included in the study. The pathological stage was pT2 in 78% (n = 92) of patients, with pT3 in 22% (n = 26). Surgical margin positivity occurred in 13.5% (n = 16) of patients. No complications were observed intraoperatively. Continence rates were 25.4% after catheter removal, rising to 88.9% in the first month, 91.5% in the third, 93.2% in the fifth, and 95.7% a year later. Thirty-five (40%) of 86 potent patients were potent in the first postoperative month, 48 patients (55.8%) were potent in the third month, and 58 patients (67.4%) were potent in the twelfth. The total complication rate was 8.4%, with no major complications observed.

Conclusion

The ultrapreservation anterior-sparing technique for patients with prostate cancer shows safe, acceptable functional and oncological results in short-term follow-up. However, long-term comparative studies with a larger number of patients are needed.

Comparison of Retzius-sparing versus standard robot-assisted radical prostatectomy for prostate cancer

INTRODUCTION AND OBJECTIVES

We aim to compare the first year oncological and functional outcomes of Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) and standard robot-assisted radical prostatectomy (RARP).

MATERIALS AND METHODS

Eighty-eight patients who underwent robotic radical prostatectomy between 2018-2019 were included. We compared the minimum one-year follow-up results of patients who underwent Rs-RARP or RARP in terms of oncological and functional outcomes. Potency was assessed with the Sexual Health Inventory for Men (SHIM) score and was defined as an erection sufficient for penetration. Continence was defined as the absence of urinary incontinence with no safety pad. Patients were evaluated in the first month of follow-up and subsequently, every three months.

RESULTS

Forty-six patients in Rs-RARP and 42 patients in the RARP group were enrolled. Catheter removal time was shorter in the Rs-RARP group (12 vs. 14 days, p = 0.001). At the 1st month visit, 41 patients (%89) were continent (no pads) in the Rs-RARP group while 25 patients (%59) were continent in the RARP group (p = 0.001). Patients who underwent Rs-RARP achieved faster recovery of urinary continence (Log-rank, p = 0.001). After one year of follow-up, 43 patients (93%) in Rs-RARP group and 38 patients (90%) in RARP group were continent (p = 0.6). Potency rates were 38.7% in Rs-RARP and 34.4% in RARP group (p = 0.28). There were no cases of biochemical recurrence in any group.

CONCLUSIONS

Rs-RARP is a feasible technique, providing early return of continence. However, overall continence rates were similar at the end of the one-year follow-up.

The Epidemiology and Population-Based Studies of Women with Lower Urinary Tract Symptoms: A Systematic Review

In this systematic review, we focused on epidemiology and population-based studies to identify recent real-world data of women with lower urinary tract symptoms. The PubMed, Scopus, and Cochrane databases were used for the literature search using the following keywords: epidemiology, population-based studies, women, female, lower urinary tract symptoms, and urinary incontinence. A total of 20 articles in the English language were found to be eligible for this review. The prevalence of LUTS in women was 11.8%-88.5%. The prevalence of storage symptoms was 23.6%-79%, voiding symptoms was 1.8%-51%, and post-micturition symptoms was 0.3%-46%. The prevalence of voiding and storage symptoms was 8.3%-26.6% and the prevalence of combined voiding, storage, and post-micturition symptoms was 6.6%-19.2%. Any incontinence was observed in 5.8%-45.8% of women. The majority of patients suffered from stress urinary incontinence with 1.9%-31.8%. The prevalence of urgency urinary incontinence and mixed-type urinary incontinence was 0.7%-24.4% and 2.1%-12%, respectively. Increased age, marital and work status, comorbidities, alcohol consumption, higher parity, vaginal delivery, instrumental delivery, prolonged labor, laceration, and post-menopausal status were found to be risk factors for lower urinary tract symptoms. The prevalence of lower urinary tract symptoms in women is increasing, especially with age. Since the worldwide prevalence of lower urinary tract symptoms remains unknown, multi-continental studies, especially in the developing world, with less heterogeneity and more standardized definitions, are needed to better evaluate real-world data in women with lower urinary tract symptoms.

Quality of life is improved after urethroplasty in women with urethral stricture

INTRODUCTION AND HYPOTHESIS

To evaluate the quality of life (QoL) in women who underwent urethroplasty for urethral stricture.

METHODS

Twenty-two women who underwent ventral labium minus graft urethroplasty were included. Patients were assessed with uroflowmetry, urethral caliber and post-voiding residual urine (PVR). American Urological Association (AUA) symptom score, Urogenital Distress Inventory (UDI)-6 and Short Form-36 (SF-36) were used to evaluate QoL. Preoperative values were compared with patients' last visit data. The cure of the surgery was defined as a maximum flow rate > 15 ml/s in uroflowmetry and no need for any further intervention.

RESULTS

Median age was 55 (40-66) years. Cure was achieved in 20 (90.3%) patients with median 37 (13-52) months follow-up duration. The median Qmax increased from 4 (0-5) ml/s to 27.5 (8-55) ml/s (p < 0.001). Median post-void residual volume (PVR) decreased from 52.5 (0-120) ml to 20(0-60) ml (p = 0.011). Both AUA symptom score [from median 30 (24-35) to 4.5 (0-20), p < 0.001] and AUA-QoL score [from median 5 (4-6) to 0(0-3), p < 0.001] decreased after surgery. Median UDI summary score at the last follow-up was 0 (0-44.4), which was 33.3 (22.2-61.05) at baseline visit. Improvement was observed in all domains except the 'Energy/Fatigue' domain of the SF-36.

CONCLUSIONS

Urethroplasty is an effective surgical method to improve patients' QoL which is impaired because of female urethral stricture.

Infectious complications after transrectal prostate biopsy is increased in patients with chronic idiopathic constipation

OBJECTIVE

This study aims to compare infectious complications after a prostate biopsy in patients with or without chronic idiopathic constipation (CIC).

METHODS

Six hundred and sixty-three patients who underwent a transrectal ultrasound-guided biopsy (TRUSBx) of the prostate between 2012 and 2018 were evaluated prospectively. Patients were divided into two groups according to their CIC status and monitored for complications. CIC was defined by the Rome III criteria. Multivariate analysis was performed to assess the risk factors.

RESULTS

Thirty-five patients (5.8%) developed a urinary tract infection (UTI) while sepsis occurred in only three cases (0.5%). CIC was found as a risk factor for infection. Infection occurred in 18.1% of the men with CIC compared to 2.3% of those without CIC (p=0.001). Sepsis occurred in 1.4% of the men with CIC compared to vs 0.2% of those without CIC (p=0.68). In multivariate analysis, CIC (OR of 9.27 and 95% CI 4.40-19.54, p<0.05) and Diabetes Mellitus (OR of 3.11 and 95% CI 1.52-6.36, p=0.002) were associated with an increased risk factor of UTI and sepsis.

CONCLUSIONS

We demonstrated that CIC is an important risk factor of infection after a prostate biopsy. Prevention is important to minimize complications after this very common worldwide procedure.

Turkish validation and reliability of the symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29) questionnaire in patients with lower urinary tract symptoms

AIMS

To evaluate the validity and reliability of the Turkish version of the Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29).

METHODS

Patients with lower urinary tract symptoms (LUTS) were included in a single-center study between January and April 2021. Patients' demographics, such as age, sex, and level of education, were recorded. The Turkish version of the LURN SI-29 and the International Prostate Symptom Score (IPSS) were administered to all patients, and the Urogenital Distress Inventory (UDI-6) was additionally administered to female patients. Construct validity was evaluated by confirmatory factor analysis. Concurrent validity was evaluated with correlations to similar measures. Internal consistency (Cronbach's alpha) and split-half reliability analyses were used to establish the scale's reliability.

RESULTS

A total of 295 participants, 35.3% females and 64.7% males, were included in the final analysis. The mean age was 56.4 ± 11.7 years. The median total LURN SI-29 scores were 38.0 (26-50) and 26.0 (18-43) for female and male patients, respectively. The LURN SI-29 scale showed a high correlation with IPSS and UDI-6 scales (r = .758, p < .001; r = .774, p < .001, respectively) in concurrent validity analysis. Cronbach's alpha coefficient of the scale and all subscales were greater than 0.70 for both female and male patients.

CONCLUSIONS

This measurement tool can potentially be used to evaluate LUTS in Turkish women and men. Further studies should be performed to reveal the clinical usefulness of this scale.

Papillary vs non-papillary access during percutaneous nephrolithotomy: Retrospective, match-paired case-control study

OBJECTIVE

The most crucial steps of percutaneous nephrolithotomy (PCNL) are the percutaneous access and dilation of the access route. Recent literature suggests that papillary access to renal calyx is the accepted method. Despite this rule, we do not always make papillary puncture and we puncture wherever we can to achieve stone-free status and reduce unnecessary access. In this study, we present our results with papillary vs non-papillary access in patients with a kidney stone.

MATERIAL AND METHODS

Two hundred and seven patients with non-papillary access and 69 patients with papillary access who had similar demographics (age, body mass index (BMI), stone size) were selected with pair match analysis (3:1). Preoperative and postoperative data were collected from the patient's chart. Operative time (from starting surgery to nephrostomy tube), drop-in hematocrit level, transfusion rate, duration of hospital stay, perioperative and postoperative complications (Clavien-Dindo Classification) and stone-free status (no or < 3 mm residual stone) were also evaluated in both groups.

RESULTS

The mean operative time was similar in between two groups. The mean hematocrit decreases not differ between the two groups (p = 0.56). In papillary group, only 2 patients (3.2%) required transfusion and only one patient (1.4%) in the non-papillary group had a transfusion with no statistically significant difference (p = 0.43). The overall complication rates were 7.1% in the papillary group and 7.2% in the non-papillary group (p = 0.89). Postoperative mean creatinine level was similar between the two groups.  Conclusions: In this study, we found that non-papillary access is a feasible option for PCNL in the terms of stone-free status and complication rates.

Comparison of surgical, oncological, and functional outcomes of robot-assisted and laparoscopic radical prostatectomy in patients with prostate cancer

OBJECTIVE

To compare the oncological and functional outcomes of robot-assisted radical prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP).

MATERIAL AND METHODS

We compared patients who underwent the RARP (n=778) and LRP (n=48) techniques for prostate cancer between January 2008 and July 2017 in our clinic. Patient demographics, preoperative and postoperative data, pathologic evaluation, continence, and potency rates were collected and analyzed retrospectively.

RESULTS

The preoperative and demographic data of the patients we included in our study were similar. The mean operation time estimated blood loss, length of hospitalization, and catheterization time were significantly shorter in the RARP group. The statistical analysis was in favor of robotic prostatectomy in the terms of the mean length of hospitalization, catheterization time, and early (<30 days) and intermediate (31-90 days) complications. Positive surgical margins and biochemical recurrence rates, and recovery of continence and erectile function, were similar in both groups.

CONCLUSION

RARP and LRP in organ-confined prostate cancer are safe and effective methods. Robotic prostatectomy has a shorter operative time, length of hospitalization, catheterization time, and lower early and late complication rates.

Safety and efficacy of PNL vs RIRS in the management of stones located in horseshoe kidneys: A critical comparative evaluation

Aim: To assess the efficacy and safety of two different techniques (Percutaneous nephrolithotomy (PNL) vs Retrograde intrarenal surgery (RIRS)) in the management of stones in patients with horseshoe kidneys (HSK). Patients and methods: Departmental files of 88 cases with radiopaque kidney stones in horseshoe kidneys undergoing two different approaches (PNL vs RIRS) were evaluated with respect to the success and complication rates of in a retrospective manner. In addition to the factors related with the procedures (success and complication rates, additional procedures), patient and stone characteristics were all well evaluated. Findings obtained in both groups were evaluated in a comparative manner with respect to the statistical significance. Results: Stone free rates were comparable in both groups after 1-week period (81.6% PNL vs 80% RIRS). As well as 3 months evaluation (84.2% PNL and 82.0% RIRS). The percentage of the cases with residual fragments (> 4 mm) were similar in both groups and while all PNL procedures were completed in one session, mean number of RIRS sessions was higher (1.22 ± 0.05). Mean duration of the procedure was slightly higher in RIRS group and based on Clavien scoring system, despite a higher risk of Hb drop noted in patients treated with PNL, all complication rates were found to be similar in both groups. Conclusion: Our results demonstrate that of the available minimally invasive treatment alternatives, both PNL and RIRS could be safe and effective alternatives for renal stone removal in patients with HSK.

Turkish validation of the urethral stricture surgery specific patient-reported outcome measure (USS-PROM) with supplemental assessment of erectile function and morbidity due to oral graft harvesting

AIMS

We validated a Turkish language version of the urethral stricture surgery specific patient-reported outcome measure (USS-PROM) in men undergoing anterior urethroplasty. We also investigated changes in erectile function (EF) and quality of life (QoL) due to oral mucosa graft (OMG) harvesting.

METHODS

The USS-PROM captures lower urinary tract symptoms (LUTS), health related QoL (HRQoL) with EQ-5D visual analogue scale (EQ-VAS). To evaluate EF and OMG morbidity, we used International Index of Erectile Function (IIEF-5) and a self-completed questionnaire, respectively. Psychometric assessment of USS-PROM included test-retest reliability, internal consistency, criterion validity, and responsiveness. Objective evidence for urethroplasty success was demonstrated with fluoroscopic imaging and urethral calibration at post-operative six months.

RESULTS

Among the 101 men included during study period, 42 had complete pre- and postoperative 6th month data for analysis. The test-retest intraclass correlation was 0.79. Cronbach's α for internal consistency of the LUTS construct was 0.79. There was a significant negative correlation between total LUTS scores and peak flow rates, both preoperatively (r = -0.478) and postoperatively (r = -0.508). Mean baseline EQ-VAS increased from 70 to 84 postoperatively (P < 0.001), indicating improved HRQoL. IIEF scores did not change significantly after urethroplasty. Early and late-term QoL impairment rates due to OMG harvesting were 28.9 and 13.1%, respectively. Three (7.1%) men required endoscopic intervention for recurrence within 6 months.

CONCLUSIONS

Turkish version of USS-PROM showed comparable psychometric properties with the original version. Complementation of this instrument with additional measures that address sexual function and OMG morbidity provides better QoL assessment for urethral reconstruction.

Long-term functional results of aspiration and sclerotherapy with ethanol in patients with autosomal dominant polycystic kidney disease: a non-randomized pilot clinical study

PURPOSE

To evaluate the long-term effect of aspiration and sclerotherapy treatment on the pain control, blood pressure regulation, and quality of life (QoL) in patients with autosomal dominant polycystic disease (ADPKD).

METHODS

Twenty-five ADPKD patients with a total of 32 dominant cysts were treated with ultrasound guidance percutaneous aspiration and 96% ethanol injection, between 2002 and 2014. Twenty-one dominant cysts of 16 patients who had a minimum of 10-year follow-up were included in this study. The level of pain [visual analog score (VAS)], narcotic usage, blood pressure and serum creatinine level, QoL questionnaire, and radiological dominant cyst size was evaluated before and after procedure, retrospectively.

RESULTS

The mean dominant cyst size was even smaller after follow-up of 10 years. Mean dominant cyst size was 7.2 ± 2.3 cm before the procedure and 0.9 ± 0.9 and 3.3 ± 1.2 cm after the one- and 10-year follow-ups, respectively (p < 0.05). VAS and QoL scores were improved after 10 years of follow-up. There was no relation between cyst size and VAS score as well as QoL questionnaire score. End-stage renal disease occurred in 50%, and there was no significant improvement in blood pressure of these patients.

CONCLUSIONS

Aspiration and sclerotherapy with ethanol is a minimal-invasive, safe, and inexpensive outpatient treatment method with acceptable short- and long-term results in ADPKD patients. Aspiration and sclerotherapy with ethanol can be an option for patients with ADPKD.
