Global prevalence of depression in chronic kidney disease: a systematic review and meta-analysis.

BACKGROUND: Chronic kidney disease (CKD) is commonly associated with psychosocial problems, especially depression, contributing to poor overall outcomes. Depression has not been given adequate priority in the management of CKD patients despite its significant adverse impact on all major outcomes. This systematic review and meta-analysis determined the pooled prevalence of clinical depression in the global CKD population and sub-populations. METHODS: PubMed, African Journals Online (AJOL), and EMBASE were systematically searched to identify published articles with relevant data. The pooled prevalence of clinical depression in the global CKD population was determined using random effects meta-analytic techniques. The study protocol was registered with PROSPERO (CRD42022382708). RESULTS: Sixty-five articles were included in this review, comprising 80,932 individuals with CKD from 27 countries. The participants' mean age ranged from 11.0 to 76.3 years. Most (70.4%) of the studies had medium methodological quality. The overall pooled prevalence of depression was 26.5% (95% CI 23.1-30.1%). Studies using the Diagnostic Statistical Manual for Mental Diseases (DSM) and International Classification of Disease (ICD) returned a pooled prevalence of 25.5% and 39.6%, respectively, p = 0.03. There was a significant difference in the pooled prevalence across regions; p = 0.002.The prevalence of depression was higher among individuals on chronic hemodialysis compared to pre-dialysis patients (29.9% versus 18.5%; p = 0.01) and among those on hemodialysis compared to peritoneal dialysis (30.6% versus 20.4%; p = 0.04). There was no significant difference between adults and children (26.8% versus 15.9%, p = 0.21). There was an increasing temporal trend in depression prevalence, though this did not achieve statistical significance (p = 0.16). CONCLUSION: Depression is common in patients with CKD. The findings of this study highlight the need for clinicians to make efforts to evaluate individuals with CKD for depression, especially those with advanced stages of the disease.

The prevalence and risk of mortality associated with intradialytic hypertension among patients with end-stage kidney disease on haemodialysis: A systematic review and meta-analysis.

INTRODUCTION: Intradialytic hypertension (IDHTN) is a common but less frequently recognised complication of haemodialysis. However, it is associated with increased overall mortality in patients on haemodialysis. This systematic review and meta-analysis aimed to determine the prevalence of IDHTN and associated mortality risk in the global haemodialysis population. METHOD: A systematic search of PubMed and EMBASE was undertaken to identify articles with relevant data published between 1990 and 2023. The pooled prevalence of IDHTN in the global haemodialysis population was determined using the DerSimonian-Laird random-effects meta-analysis. The pooled hazards ratio for mortality in patients with IDHTN was also computed from the studies that reported mortality among haemodialysis patients with IDHTN. The study protocol was registered with PROSPERO (CRD42023388278). RESULTS: Thirty-two articles from 17 countries were included, with a pooled population of 127,080 hemodialysis patients (median age 55.1 years, 38.2% females). Most studies had medium methodological quality (53.1%, n = 17). The overall pooled prevalence of IDHTN was 26.6% [(95% CI 20.2-33.4%), n = 27 studies, I2 = 99.3%, p<0.001 for heterogeneity], with significant differences depending on the definition used. The pooled proportion of haemodialysis sessions with IDHTN was 19.9% [(95% 12.5-28.6%, n = 8 studies, I2 = 99.3%, p<0.001 for heterogeneity)] with significant differences across the different definition criteria. The p-value for the Begg test was 0.85. The median pre-dialysis blood pressure was not significantly associated with IDHTN. The pooled hazard ratio for mortality was 1.37 (95% CI 1.09-1.65), n = 5 studies, I2 = 13.7%, and p-value for heterogeneity = 0.33. CONCLUSION: The prevalence of IDHTN is high and varies widely according to the definition used. A consensus definition of IDHTN is needed to promote uniformity in research and management. The increased mortality risk forecasted by IDHTN highlights the need for optimal blood pressure control in patients on hemodialysis.

Translational and linguistic validation of the Arabic version of dysfunctional voiding symptom score questionnaire.

INTRODUCTION: Dysfunctional voiding is a multifactorial condition that encompasses a wide variety of symptoms rendering its diagnosis a challenging process. In this setting, several tools have been proposed to aid the diagnosis of this disease among which is the Dysfunctional Voiding Symptom Score (DVSS). The DVSS has been translated and validated to different languages including Japanese, Thai, Chinese, Serbian, and Portuguese. The aim of the current study is to translate and cross-culturally validate the DVSS into the Arabic language. MATERIAL AND METHODS: The DVSS was translated and culturally adapted to the Arabic language following the standards of the ISPOR for the translation and cultural adaptation process for patient-reported outcomes measures. Subsequently, the translated version underwent a pre-test on 15 patients with dysfunctional voiding. Afterwards, the translated version was filled by 82 pediatric patients and/or their parents with dysfunctional voiding and then the same questionnaire was refilled by the patients and their families one week later at home. Finally, a group of healthy children and/or their parents were recruited to fill the questionnaire as a control group. Cronbach's alpha, Pearson's correlation, and Interclass correlation were used to assess for internal consistency and reliability between test-retest of the Arabic version. RESULTS: The mean total score of DVSS for the case and control groups was 16.66 ± 6.07 and 6.11 ± 3.36, respectively (P < 0.001). The Arabic-DVSS showed excellent internal consistency (Cronbach's α > 0.9) for all the questions except Q1, Q3, Q6, and Q7 that showed good internal consistency. DISCUSSION: Translational and linguistic validation of the DVSS questionnaire into Arabic language is an important step toward its introduction in the clinical practice in Arabic countries; however, this step has also to consider the cultural variations between countries and not just linguistic translation. Generally, the Arabic-DVSS showed a satisfactory test-retest internal consistency and reliability with an excellent Cronbach's α (0.982) and ICC (0.962) for the total score of the Arabic-DVSS. Yet, the main limitation of this study was that it was only advocated for the translation and validation of the Arabic-DVSS and did not assess its value in patients' follow-up. CONCLUSION: The Arabic version of the DVSS is reliable and valid to help in the evaluation of DV in children of Arabic countries.

Creation and validation of the harmonized Arabic version of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP).

Objectives: Tocreate and validate a translated Arabic version of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP), a validated patient-reported outcome (PRO) widely used for assessing the quality of life in patients with prostate cancer (PCa). Patients and Methods: Using the established protocol as defined by the Professional Society for the Health Economics and Outcomes Research (ISPOR) for translating patient care questionnaires, a harmonised translated Arabic version of EPIC-CP was created. The questionnaire was tested in native Arabic speakers from four different Arabic countries (Saudi Arabia, United Arab Emirates, Jordan, and Kuwait). Cronbach's alpha and interclass coefficient correlation (ICC) analyses were used to test the internal consistency and test-retest reliability, respectively. In addition, PCa characteristics were collected for participants. Results: In total, 168 patients with PCa participated in the study (39 from Saudi Arabia, 23 from United Arab Emirates, 65 from Jordan, and 41 from Kuwait). In all, 52 (31%) participants repeated the questionnaire for test-retest reliability analysis. The median (interquartile range [IQR]) age of patients included in the study was 66 (61-71) years. The median (IQR) PSA level was 9.8 (6-19) ng/mL. Most patients had Grade Group 2 PCa at diagnosis (31%), clinical stage cT1 (42%), managed primarily by urology (79%), and the primary treatment was radical prostatectomy (71%). The total Cronbach's alpha coefficient was 0.84 demonstrating an acceptable internal consistency. The total ICC was also acceptable at 0.64. Conclusion: The Arabic version of the EPIC-CP is a reliable and valid tool for assessing health-related quality of life for Arabic patients with PCa.

Hospitalization patterns in HD patients in the Kingdom of Saudi Arabia: A comprehensive cohort study.

INTRODUCTION: The rate of hospitalization represents a morbidity indicator in HD patients. The study aimed to evaluate hospitalization patterns in a large HD cohort. METHODS: All DaVita-KSA HD patients from October 2014 to December 2019 were included. Demographical and clinical characteristics and hospitalization data were recorded. Less than 24 h admission was excluded. Overall and cause-specific hospitalization rates were calculated. RESULTS: During the follow-up period, 3982 patients with a mean age of 52.5 ± 16.8 years, 2667 hospitalizations were recorded in 34.1% of the patients and 45.6% had repeated admissions. Infectious causes accounted for 26.6% of all recorded causes vs. 15.6% for cardiovascular complications. The median hospital stay length was 11 days, while the overall annual hospitalization rate of 34.9% and the annual duration of 3.7 days per patient. Hospitalized patients had a higher risk of mortality (p < 0.001). CONCLUSION: Infectious complications were the leading cause of hospitalization and had the longest hospital stay.

Value of early second session shock wave lithotripsy in treatment of upper ureteric stones compared to laser ureteroscopy.

PURPOSE: The safety and efficacy of early second session shock wave lithotripsy (SWL) compared with laser ureteroscopy (URS) for the treatment of upper ureteric stones were evaluated. METHODS: From January to October 2019, 108 patients with upper ureteric stones (< 1.5 cm and ≤ 1000 Hounsfield unit (HU)) were randomized into SWL and laser URS groups. The second SWL session was performed within 48-72 h of the first session. Using plain abdominal X-ray and ultrasonography, patients were evaluated 48-72 h after the first SWL session and one week after the second and third SWL sessions or one week after URS. The procedure was considered a success when no additional procedures were needed to clear the stone. To determine the stone-free rate (SFR), noncontrast computed tomography of the urinary tract was performed three months postoperatively. RESULTS: In the SWL group, the success rates were 92.6% and 94.4% after the second and third sessions. The SFR was 96.2% in the laser URS group. The success rates were not significantly different between the second and third SWL sessions versus the laser URS (p = 0.418 and 0.660, respectively). Operative and fluoroscopy times were significantly longer in the SWL group (p = 0.001), and JJ stent insertions were needed after laser URS. CONCLUSION: Ultraslow full-power SWL treatment of patients with upper ureteric stones (< 1.5 cm and ≤ 1000 HU) with an early second session is safe and effective compared to laser URS. Patients who do not respond to early second SWL session should be shifted to another treatment modality.

Ultraslow full-power shock wave lithotripsy protocol in the management of high attenuation value upper ureteric stones: A randomized comparative study.

OBJECTIVES: To evaluate the efficacy and safety of ultraslow full-power shock wave lithotripsy protocol in the management of high attenuation value upper ureteric stones compared with slow-rate, power-ramping shock wave lithotripsy. METHODS: This was a randomized trial enrolling patients with a single high attenuation value (≥1000 HU) upper ureteric stones between January 2019 and July 2019. Ultraslow full-power shock wave lithotripsy (54 patients) was applied at a rate of 30 shock waves/min with power ramping from 6 to 18 kV for 100 shock waves, then a safety pause for 2 min, followed by ramping 18-22 kV for 100 shock waves, then a safety pause for 2 min. Then, full power (22 kV) was maintained until the end of the session. Slow-rate, power-ramping shock wave lithotripsy (47 patients) was applied at a rate of 60 shock waves/min with power ramping from 6 to 10 kV during the first 500 shock waves, then from 11 to 22 kV during the next 1000 shock waves, then maintained on 22 kV in the last 1500 shock waves. Up to three sessions were carried out with a follow up 3 months after the last session. The primary outcome was the stone-free rate. Perioperative data of the two protocols were compared. RESULTS: There was no significant difference in preoperative data. The stone-free rate was significantly higher in ultraslow full-power shock wave lithotripsy after single (92.6% vs 23.4%) and multiple (96.3% vs 63.8%) sessions. Most complications were mild, with no significant difference between both groups (9.3% vs 12.8%; P = 0.573). Logistic regression analysis identified ultraslow full-power shock wave lithotripsy protocol as the only significant independent factor for the stone-free rate (odds ratio 12.589, P = 0.025). CONCLUSION: Ultraslow full-power shock wave lithotripsy for high attenuation value upper ureteric stones is associated with a significantly higher stone-free rate, and with mild complications that are comparable to those of standard shock wave lithotripsy.

Relation of baseline prostate volume to improvement of lower urinary tract symptoms due to tamsulosin monotherapy in benign prostatic hyperplasia: An exploratory, multicenter, prospective study.

AIMS: The aim of the study was to investigate the relation between baseline prostate volume (PV) and the improvement of lower urinary tract symptoms (LUTS) induced by tamsulosin monotherapy after 2-year follow-up in Egyptian benign prostatic hyperplasia (BPH) patients. SETTINGS AND DESIGN: This was a prospective comparative multicenter study. SUBJECTS AND METHODS: Three hundred and eighty-one BPH patients were included in the study from January 2014 to January 2017. The patients were divided according to their PV into two groups. Group A included patients with small-sized prostate (≤40 ml) and Group B included those with PV larger than 40 ml. Full evaluation was done at presentation. The patients are followed up at 6, 12, and 24 months of continued medical treatment with tamsulosin 0.4 mg once daily. STATISTICAL ANALYSIS USED: Data were coded and entered using the Statistical Package for the Social Sciences version 24. Data were summarized using mean and standard deviation in quantitative data. Comparisons between quantitative variables were done using unpaired t-test or the nonparametric Mann-Whitney test. A comparison between paired measurements in the same person was done using paired t-test (Chan, 2003). P < 0.05 was considered as statistically significant. RESULTS: The mean age was 60.1 ± 7.2 years. The mean value of the International Prostate Symptom Score (IPSS) was recorded for the 381 patients at presentation. In Group A, the mean value of IPSS was 20.44 ± 3.18, whereas in Group B, the mean value of IPSS was 21.23 ± 3.5. There was a significant improvement in symptoms (Qmax-IPSS) in both groups, but we found that this improvement was significantly better in Group A (P = 0.017). CONCLUSIONS: PV is an important prognostic factor affecting the improvement of the LUTS by α1-blocker monotherapy. Tamsulosin monotherapy may not be enough for large prostate (>40 mg) to maintain adequate symptom relief, and it is better to start with other medical options such as combined therapy or early nonmedical therapy. Starting α1-blocker monotherapy in smaller prostates may be of benefit in symptomatic patients without considering watchful waiting.

Percutaneous nephrostomy versus JJ ureteric stent as the initial drainage method in kidney stone patients presenting with acute kidney injury: A prospective randomized study.

OBJECTIVE: To compare percutaneous nephrostomy tube versus JJ stent as an initial urinary drainage procedure in kidney stone patients presenting with acute kidney injury. METHODS: Between January 2017 and January 2019, 143 patients with acute kidney injury secondary to obstructive kidney stone were prospectively randomized into the percutaneous nephrostomy tube group (71 patients) and JJ stent group (72 patients) at Beni-Suef University Hospital, Beni-Suef, Egypt. Exclusion criteria included candidates for acute dialysis, fever (>38°C), pyonephrosis, pregnancy and uncontrolled coagulopathy. The period required for serum creatinine normalization, failure of insertion, operative and fluoroscopy time were recorded. Definitive stone management for proximal ureteral stones >1.5 cm consisted of percutaneous nephrolithotomy for the percutaneous nephrostomy group and ureteroscopic laser lithotripsy for the JJ stent group. For stone size <1.5 cm, ureteroscopy or shockwave lithotripsy was carried out for both groups. Percutaneous nephrolithotomy was carried out for renal stones >2 cm, and shockwave lithotripsy for stones <2 cm. Distal and mid ureteral stones were treated by ureteroscopy. RESULTS: The percutaneous nephrostomy group had shorter operative time (P = 0.001). There was no significant difference in the recovery period for normalization of serum creatinine between both groups (P = 0.120). Procedural failure, ureteric mucosal injury and perforations increased in the case of male sex, stone size >1.5 cm and upper ureteric stones in the JJ stent group. Procedural failure, pelvic perforations and intraoperative bleeding increased in case of male sex, mild hydronephrosis and stone size >2.5 cm in the percutaneous nephrostomy group. Suprapubic pain, urethral pain and lower urinary tract symptoms were significant in the JJ stent group. The presence of a JJ stent directed us toward ureteroscopy (P = 0.002) and the presence of a percutaneous nephrostomy directed us toward percutaneous nephrolithotomy (P = 0.001). CONCLUSIONS: Percutaneous nephrostomy facilitates subsequent percutaneous nephrolithotomy, especially when carried out by a urologist, and it has a higher insertion success rate, a shorter operative time and a lesser incidence of postoperative urinary tract infection than a JJ stent. A JJ stent facilitates subsequent ureteroscopy, but operative complications can increase in the case of proximal ureteral stones >1.5 cm.

Ultraslow full-power shock wave lithotripsy versus slow power-ramping shock wave lithotripsy in stones with high attenuation value: A randomized comparative study.

OBJECTIVES: To compare the efficacy and safety of ultraslow full-power versus slow rate, power-ramping shock wave lithotripsy in the management of stones with a high attenuation value. METHODS: This was a randomized comparative study enrolling patients with single high attenuation value (≥1000 Hounsfield unit) stones (≤3 cm) between September 2015 and May 2018. Patients with skin-to-stone distance >11 cm or body mass index >30 kg/m2 were excluded. Electrohydraulic shock wave lithotripsy was carried out at rate of 30 shock waves/min for group A versus 60 shock waves/min for group B. In group A, power ramping was from 6 to 18 kV for 100 shock waves, then a safety pause for 2 min, followed by ramping 18-22 kV for 100 shock waves, then a safety pause for 2 min. This full power (22 kV) was maintained until the end of the session. In group B, power ramping was carried out with an increase of 4 kV each 500 shock waves, then maintained on 22 kV in the last 1000-1500 shock waves. Follow up was carried out up to 3 months after the last session. Perioperative data were compared, including the stone free rate (as a primary outcome) and complications (secondary outcome). Predicting factors for success were analyzed using logistic regression. RESULTS: A total of 100 patients in group A and 96 patients in group B were included. The stone-free rate was significantly higher in group A (76% vs 38.5%; P < 0.001). Both groups were comparable in complication rates (20% vs 19.8%; P = 0.971). The stone-free rate remained significantly higher in group A in logistic regression analysis (odds ratio 24.011, 95% confidence interval 8.29-69.54; P < 0.001). CONCLUSIONS: Ultraslow full-power shock wave lithotripsy for high attenuation value stones is associated with an improved stone-free rate without affecting safety. Further validation studies are required using other shock wave lithotripsy machines.

Predictive value of the immediate effect of first dose of tamsulosin on lower urinary tract symptoms improvement in benign prostatic hyperplasia patients.

OBJECTIVES: The objective is to study the effect of tamsulosin within hours after the first dose and its prediction of the future improvement of LUTS. MATERIALS AND METHODS: From May 2016 until August 2017, 340 patients aged over 40 years with benign prostatic hyperplasia (BPH)-related symptoms were prospectively enrolled; 0.4 mg tamsulosin for 3 months was given. The first visit was before beginning of tamsulosin; uroflowmetry (UFM), postvoid residual urine volume (PVR), international prostate symptom score (IPSS), and quality of life (QoL) were measured. The second visit was after 6 h from the administration of tamsulosin. UFM and PVR were measured. The third visit was after 1 month and the fourth visit was after 3 months, on which UFM, PVR, IPSS, and QoL were also measured. RESULTS: The mean patients' age was 63 ± 6.18 and the mean prostate volume was 52.23 ± 24.59 cc. The mean Qmax at 1st, 2nd, 3rd, and 4th visits was 10.28 ± 3.06 s, 14.58 ± 4.84 s, 14.46 ± 4.94 s, and 14.28 ± 5.07 s, respectively, P = 0.04. The mean voiding time at 1st, 2nd, 3rd, and 4th visits was 41.24 ± 27.18 s, 33.84 ± 18.14 s, 31.96 ± 22.02 s, and 30.14 ± 17.52 s, respectively, P = 0.03. The mean PVR at 1st, 2nd, 3rd, and 4th visits was 46.40 ± 22.14 ml, 27.76 ± 26.10 ml, 25.16 ± 28.36 ml, and 25.58 ± 28.10 ml, respectively, P = 0.001. The first dose of tamsulosin significantly increases Qmax and decreases voiding time and residual urine (RU); there was no statistical significant difference between 1st dose, 1 and 3 months in Qmax, voiding time, and RU. QOL and IPSS were significantly improved after 1 and 3 months, P < 0.001. CONCLUSION: The first dose of tamsulosin improves UFM and predicts the mid-term change in UFM as well as IPSS and QoL indices in the treatment of BPH-related LUTS.

Outcome of Botulinum Toxin-A intraprostatic injection for benign prostatic hyperplasia induced lower urinary tract symptoms: A prospective multicenter study.

INTRODUCTION: Our aim was to determine the factors predicting the outcome of intraprostatic injection of Botulinum Toxin-A (BTX-A) in the treatment of benign prostatic hyperplasia (BPH)-induced lower urinary tract symptoms (LUTS) and to evaluate its efficacy and safety. METHODS: Between September 2016 and May 2018, 45 Egyptian patients, with BPH-induced LUTS were included; the indication was a failure of medical treatment, unfit, or refusing surgical intervention. Measurements of prostate size by TRUS, total PSA level before and 12 weeks after injection. IPSS, uroflow, and postvoiding residual urine (PVR) were measured before injection, 2, 4, 8 and 12 weeks postinjection. 100 U BTX-A vial was diluted with 10 mL of saline then injected into the transition zone at base and midzone of the prostate by TRUS. RESULTS: The mean patients' age was 64.4 ± 6.6 years. Mean baseline IPSS 24.06 decreased to 18.75 at 2 weeks and progressively decreased to 16.37 at 12 weeks (P < 0.001), Q max of 9.08 mL/s. increased to 10.44 at 2 weeks and 11.44 at 12 weeks (P < 0.001), mean prostate volume was 67.44cc; decreased to 66.06cc (P < 0.001) at 12 weeks and mean residual urine was 82.62 mL and decreased to 57.66 mL at 12 weeks. DISCUSSION: Intraprostatic injection of BTX-A as modality treatment of LUTS/BPH significantly improve IPSS, Q max , PVR, and decrease prostate volume. We can suspect better results with this line of treatment in patients with IPSS ≤ 22 and Q max ≤ 10 mL/min and prostate volume ≤ 56.5cc.

PCA3-based nomogram for predicting prostate cancer and high grade cancer on initial transrectal guided biopsy.

BACKGROUND: To develop a validated prostate cancer antigen 3 (PCA3) based nomogram that predicts likelihood of overall prostate cancer (PCa) and intermediate/high grade prostate cancer (HGPCa) in men pursuing initial transrectal prostate biopsy (TRUS-PBx). METHODS: Data were collected on 3,675 men with serum prostate specific antigen level (PSA) ≤ 20 ng/ml who underwent initial prostate biopsy with at least 10 cores sampling at time of the biopsy. Two logistic regression models were constructed to predict overall PCa and HGPCa incorporating age, race, family history (FH) of PCa, PSA at diagnosis, PCA3, total prostate volume (TPV), and digital rectal exam (DRE). RESULTS: One thousand six hundred twenty (44%) patients had biopsy confirmed PCa with 701 men (19.1%) showing HGPCa. Statistically significant predictors of overall PCa were age (P < 0.0001, OR. 1.51), PSA at diagnosis (P < 0.0001, OR.1.95), PCA3 (P < 0.0001, OR.3.06), TPV (P < 0.0001, OR.0.47), FH (P = 0.003, OR.1.32), and abnormal DRE (P = 0.001, OR. 1.32). While for HGPCa, predictors were age (P < 0.0001, OR.1.77), PSA (P < 0.0001, OR.2.73), PCA3 (P < 0.0001, OR.2.26), TPV (P < 0.0001, OR.0.4), and DRE (P < 0.0001, OR.1.53). Two nomograms were reconstructed for predicted overall PCa probability at time of initial biopsy with a concordance index of 0.742 (Fig. 1), and HGPCa with a concordance index of 0.768 (Fig. 2). CONCLUSIONS: Our internally validated initial biopsy PCA3 based nomogram is reconstructed based on a large dataset. The c-index indicates high predictive accuracy, especially for high grade PCa and improves the ability to predict biopsy outcomes.

Combined Vaginal Pelvic Floor Electrical Stimulation (PFS) and Local Vaginal Estrogen for Treatment of Overactive Bladder (OAB) in Perimenopausal Females. Randomized Controlled Trial (RCT).

OBJECTIVE: To evaluate the efficacy of combined vaginal pelvic floor electrical stimulation (PFS) and local vaginal estrogen in treatment of female overactive bladder (OAB). MATERIAL AND METHODS: This is a randomized controlled trial carried out on 315 perimenopausal females with OAB who were randomly allocated into 3 equal groups. Group A underwent PFS using vaginal probes twice weekly for 12 sessions. Group B received local vaginal estrogen, whereas group C received both PFS and local estrogen. All patients were evaluated by a voiding diary, quality-of-life questionnaire, vaginal examination, urine analysis, blood sugar, ultrasonography, and urodynamic study before and after therapy. Patients were followed up 1 week, 3, and 6 months post-therapy. The analyzed variables included day and night time frequency, incontinence episodes, urgency, quality of life, detrusor overactivity), and functional bladder capacity). Outcome measure was urge incontinence. RESULTS: Within each group, there was a statistically significant improvement in all variables after treatment. Improvement of urgency was better in group C than in groups A and B (P = .000, .009). Improvement of incontinence was better in groups A and C than in group B (P = .005, .004). Follow-up showed worsening of symptoms within 6 months in all groups except incontinence in group C. CONCLUSION: Vaginal PFS and estrogen found to be effective in treating OAB symptoms in perimenopausal females. Estrogen seems to augment the effect of PFS especially in the treatment of urgency incontinence and can delay its recurrence.

Low risk patients benefit from extreme anterior apical sampling on initial biopsy for prostate cancer diagnosis.

BACKGROUND: To assess the effect of additional extreme apical sampling on prostate cancer (PCa) detection and aggressiveness in patients with standard risk versus high risk of a positive biopsy. METHODS: Three thousand fifty three men were reviewed from our institution review board approved prostate biopsy database. Two thousand five hundred and twenty one underwent biopsy with 12 cores while 532 underwent 14 core sampling (2 extra cores from the extreme anterior apex). Patients were stratified into one of two risk groups: (1) standard risk of PCa (elevated prostate specific antigen (PSA) < 10 ng/ml, normal digital rectal exam (DRE), and no lesions on transrectal ultrasound (TRUS)), and (2) higher risk of PCa (PSA > 10 ng/ml and/or abnormal DRE and/or lesion on TRUS). Prostate cancer detection and disease characteristics were compared between the biopsy schemes stratified by risk of a positive biopsy. RESULTS: PCa detection with 14 core sampling was more likely in all patients (OR 1.339, 95% CL 1.070-1.676) and in men with standard risk (OR 1.334, 95% CL 1.007-1.769). A greater median number of positive cores (3 vs. 2) and a higher maximum cancer % per core (40% vs. 25%) were seen in the 14 core cohort when stratified to standard risk. Gleason ≥7 was more likely detected with 14 cores in the standard risk group (55.6% vs. 45.2%). Differences in PCa detection and Gleason ≥7 between biopsy techniques were not noted in the higher risk group. CONCLUSION: Extreme apical sampling increases aggressive cancer detection on initial biopsy, especially in patients with standard risk of PCa.

Percutaneous nephrolithotomy in the oblique supine lithotomy position and prone position: a comparative study.

OBJECTIVES: To compare the safety, efficacy, and complications of percutaneous nephrolithotomy (PCNL) in the oblique supine lithotomy position vs the prone position in a randomized comparative study. PATIENTS AND METHODS: The study included 101 and 102 patients in the oblique supine lithotomy position and prone position, respectively. Inclusion criteria were renal and upper ureteral stones. Exclusion criteria were uncorrectable bleeding disorders, active urinary tract infection, and pregnancy. RESULTS: Both the groups were comparable regarding the male/female ratio, stone size, and site. No significant differences were found in terms of the stone-free rate, blood transfusion rate, and complication rates. Significant differences were reported in mean hemoglobin loss (-1.03 and -2.18 g/dL), mean operative time (86.16 and 111.7 minutes), and mean hospital stay (49.88 and 81.2 hours) in the supine and prone positions, respectively, and anesthesiological parameters (the mean blood pressure decreased by 2 and 14.06 mm Hg, the mean heart rate changed by -0.82 and +13.28 beat/minute, and the peak air way pressure changed by +1.08 cm H2O and +7.56 cm H2O in the supine and prone positions, respectively). CONCLUSIONS: PCNL in both positions was equally successful with no significant differences in complications. PCNL in the oblique supine lithotomy position was superior to PCNL in the prone position regarding operative time, hospital stay, and effects on respiratory and cardiovascular status, making it more comfortable for patients and anesthesiologists. Morbidly obese patients, patients with cardiologic disorders, and patients with pulmonary obstructive airway disease need further studies to show if they would benefit from these differences. Additionally, it is more comfortable for the surgeon with little challenges added in the initial puncture.
