RESUMO
Evaluating bladder outlet obstruction (BOO) in patients with prostatic enlargement may reflect the severity of the disease and aid in predicting the treatment outcome. Objectives: To determine the sonological correlation between intravesical prostatic protrusion and bladder outlet obstruction in patients with symptomatic benign prostatic enlargement. Methods: This prospective study was conducted over one year at the Department of Radiology, University College Hospital, Ibadan. A transabdominal ultrasound scan of the urinary bladder and prostate gland was carried out on patients with prostatic enlargement and BOO. The intravesical prostatic protrusion, pre-and post-void urine volumes, prostate volume and bladder wall thickness were measured. Results: A total of 132 men aged 43 to 90 years (mean age: 63.8±8.64 years) were studied. The median size of the intravesical prostatic protrusion (IPP) was 7.25 mm (IQR: 0.00 mm; 14.9 mm). The mean prostate volume was 63.3ml±36.0ml. Most subjects (55; 41.7%) had a prostate volume above 60ml, and most patients (101, 77.2%) had bladder wall thickness less than 5mm. The mean bladder wall thickness was 4.26mm±1.54mm. There was a statistically significant correlation between IPP and pre-void urine volume and prostate volume (p = 0.002 and <0.001, respectively). Patients over 70 years had increasing IPP and post-void urine, which lacked statistical significance (p =0.15). Conclusion: The severity of bladder outlet obstruction was reflected in the pre-void urine volume, which correlated with the size of IPP

Post-Void Residual (PVR) volume of urine is the amount of urine retained in the bladder after a voluntary void that is measured by catheterization or non-invasively by ultrasonography. The increased value of PVR act as a diagnostic tool in a urological pathology such as a neurological disease/injury to the bladder, mechanical obstruction, infection or medication induced urinary retention. A PVR less than 50ml signifies adequate bladder emptying. The present case is of 3.1mm non-obstructing left renal calculus and Grade III prostatomegaly with increased Post Void Residual urine (91ml). Renal calculi and prostatomegaly, both are common obstructive uropathies which interferes with the normal outflow of urine. Treatment is aimed at relieving the symptoms and to treat the underlying cause as well. The treatment strategies that can be followed are catheterization, stenting, surgery, lithotripsy, hormonal therapy and antibiotic therapy. The Ayurvedic formulation, Varunadi Kashaya and Dashmool Churna are Vata kapha pacifying drugs. With its Mutrala, Deepana, Anulomana, Shothghana, Shoolghana properties, it had successfully eliminated renal calculus, decreased the prostate size and ultimately, lowered the PVR value as evidenced in USG report. There is a considerable relief in the troublesome urological symptoms- dysuria, dribbling micturition, weak urine stream, inadequate bladder emptying and abdominal pain.
RESUMO
Objective:To explore the efficacy and safety of intravesical electrical stimulation (IVES) combined with a training for bladder motor and sensory dysfunction in the treatment of neurogenic underactive bladder(UAB).Methods:A prospective, single-blind, randomized controlled trial was used to study neurogenic UAB patients admitted to the China Rehabilitation Research Center from October 2019 to May 2021. Inclusive criteria included age≥18 years old, the patients who have been diagnosed as neurogenic UAB and the course of disease being more than 3 months; patients who have been undergone intermittent catheterization to empty the bladder or patients indicated for intermittent catheterization (post-void residual urine accounts for more than 40% of the functional bladder volume), voluntary signing of written informed consent, able to communicate well with researchers and comply with the requirements of the whole trial, and the patient not undergoing any treatment other than oral medication before IVES. Exclusion criteria included patients with low bladder compliance by urodynamic examination(<20 ml/cmH 2O), patients with mechanical outflow obstruction, patients with complete spinal cord injury, the patients with symptomatic urinary tract infection which was not cured, patients with hydronephrosis or bladder-ureteral reflux, patients with renal insufficiency(serum creatinine greater than 1.5 times of the upper limit of normality), patients with malignant tumors of the bladder or prostate, overactive bladder, Alzheimer's disease, brain atrophy, acute cerebrovascular disease, or cognitive impairment, patients who were pregnant or planning to be pregnant, bladder mucosa injury, patients with pacemakers or defibrillators, those who participated in other clinical trials 3 months before the study, and other circumstances that the researcher consider it is not suitable to be involved in this study. The patients were randomly divided into experimental group and control group according to the ratio of 1∶1. The experimental group used conventional transurethral insertion of bipolar catheter electrodes for IVES combined with bladder motor and sensory dysfunction training, and the control group underwent IVES with open circuit combined with bladder motor and sensory dysfunction training. The stimulation parameters of the two groups were two-way square wave, 1-30 mA intensity, 10-20 Hz frequency, 200 μs pulse width, once a day, lasting 30 minutes for each treatment, and for continuous 20 working days. The post-void residual urine, voiding efficiency, 24-hour intermittent catheterization times, first sensation of bladder filling volume and American Urological Association Symptom Index Quality of Life(AUA-SI-QOL) scores were recorded before and at the end of treatment. The adverse events during the treatment were recorded. Results:Fifty-two patients were selected and 50 patients completed the trial, including 26 patients in the experimental group and 24 patients in the control group. Before treatment, there were no significant differences in gender[16(male)/10(female)vs.13(male)/11(female), P=0.598], age [(40.7±13.5)years vs.(38.5±12.3)years, P=0.543], course of disease[0.71(0.42, 1.63)years vs.0.79(0.42, 1.50)years, P=0.695], post-void residual urine[300(193, 400)ml vs.325(178, 380)ml, P=0.724], voiding efficiency[17%(0, 47.8)% vs.21%(0, 38.0)%, P=0.960], 24-hour intermittent catheterization times[4(2, 4)vs.3(2, 4), P=0.692], first sensation volume during bladder filling[(325.8±74.3)ml vs.(307.5±75.0)ml, P=0.391] or AUA-SI-QOL scores[5(4, 5)vs.4(4, 5), P=0.313] between the experimental group and the control group. At the end of treatment, the post-void residual urine, first sensation volume during bladder filling and AUA-SI-QOL scores of the experimental group were significantly lower than those of the control group [250(40, 350)ml vs.300(200, 390)ml, P=0.034; (276.5±68.8)ml vs.(315.4±67.3)ml, P=0.049; 4(2, 4)vs.4(3, 5), P=0.024], and the voiding efficiency was significantly higher than that of the control group[33%(14.5, 84.5)% vs.18%(0, 35.8)%, P=0.041], but there was no significant difference in the number of 24-hour intermittent catheterization between the two groups [3(1, 4)vs.3(2, 4), P=0.174]. In the control group, there were no significant changes in post-void residual urine, voiding efficiency, 24-hour intermittent catheterization times, first sensation volume during bladder filling and AUA-SI-QOL scores before and after treatment [325(178, 380)ml vs.300(200, 390)ml, P=0.832; 21%(0, 38.0)% vs.18%(0, 35.8)%, P=0.943; 3(2, 4)vs.3(2, 4), P=0.239; (307.5±75.0)ml vs.(315.4±67.3)ml, P=0.257; 4(4, 5)vs.4(3, 5), P=0.157]. In the experimental group, there were significant improvements in post-void residual urine, voiding efficiency, 24-hour intermittent catheterization times, first sensation volume during bladder filling and AUA-SI-QOL scores before and after treatment [300(193, 400)ml vs.250(40, 350)ml, P<0.001; 17%(0, 47.8)% vs.33%(14.5, 84.5)%, P<0.001; 4(2, 4)vs.3(1, 4), P=0.011; (325.8±74.3)ml vs.(276.5±68.8)ml, P<0.001; 5(4, 5)vs.4(2, 4), P<0.001]. During the treatment period, 1 case of abdominal discomfort occurred in the experimental group and 1 case of urethral discomfort in the control group. After adjusting the stimulation intensity and catheter position, the discomfort disappeared without other serious adverse events. Conclusions:IVES combined with bladder motor sensory dysfunction training can not only effectively improve the bladder emptying efficiency and bladder sensation in patients with neurogenic UAB, but also be safe and easy to operate.
RESUMO
Objectives: This study aimed to assess the accuracy of post-void residual (PVR) urine volume measurements in patients with moderate bladder outlet obstruction. Materials and Methods: This prospective observational study was conducted between January and December 2019. The inclusion criteria were male patients with symptoms of moderate bladder outlet obstruction. On the other hand, patients with a history of diabetes, symptoms of urinary tract infection, and positive urine for pyuria, as well as patients using medications, such as diuretics, alpha-blockers, and anticholinergic drugs, were excluded. The patients were asked to drink 1000 mL of water one to two hours before the initial ultrasound scan. Pre-void bladder capacity was measured, followed by a post-void ultrasound for residual urine volume measurement at three intervals: immediately after voiding, 15-20 minutes after the first void, and one week later with an empty bladder. Assessment of per-void capacity was carried out, based on the patient's subjective sensation of bladder fullness (a strong desire to void). Results: A total of 78 male patients, with the mean age of 60 years, were included in this study (27 cases in group I; 37 cases in group II; and 14 cases in group III). The mean PVR volume was 92 mL in the first measurement, 62 mL in the second measurement, and 60 mL in the third measurement. Significant differences were found between the first and second PVR measurements and between the first and third PVR measurements (P<0.05). However, no significant difference was found between the second and third PVR measurements (P=0.107). On the other hand, significant differences were found between groups I and II and between groups I and III (P<0.05) in the three PVR measurements. Nevertheless, there was no significant difference between groups II and III in the three PVR measurements (P=0.204, 0.56, and 0.487 for the first, second, and third PVR measurements, respectively). Conclusion: A bladder ultrasound must be performed and interpreted carefully to avoid further unnecessary medications, investigations, or procedures. We recommend a second PVR measurement in patients with bladder outlet obstruction. Also, it is suggested to conduct similar studies in different conditions to confirm our findings.

Background: To evaluate the efficacy and safety profile of alpha-1A receptor subtype specific antagonist-tamsulosin in benign prostatic hyperplasia.Methods: An open label, non-randomised, prospective, single centred study who were visiting urology department with confirmed diagnosis of benign prostatic hyperplasia (BPH) were included in the study. Thirty patients with BPH were prescribed tamsulosin and were followed up to three months. The initial or baseline data collected were identification of the patients such as international prostate symptom score (IPSS), prostate specific antigen, urine analysis, and ultrasonography of prostate including post void residual urine. The patients were followed up to 3 months to measure clinical and laboratory outcomes (IPSS score, post void residual urine, uroflow rates etc.).Results: In our study, patients receiving tamsulosin 0.4 mg once daily showed a significant improvement in post-void residual urine (PVRU), uroflow rates and IPSS score. The improvements in the above parameters were found to be statistically insignificant at first and third month of follow-up.Conclusions: In our study, tamsulosin an alpha-1A receptor subtype specific antagonist showed significant improvement in BPH symptoms and the drug was well tolerated.
RESUMO
Background: The objective of the present study was to observe the post void residual volume (PVRV) in women with pelvic organ prolapse (POP) pre and postoperatively and to correlate stage of prolapse with lower urinary tract symptoms and quality of life in women with pelvic organ prolapse.Methods: This is a prospective observational cohort study of 100 women with symptomatic pelvic organ prolapse of stage II or greater. Patients were admitted for Vaginal hysterectomy with pelvic floor repair for pelvic organ prolapse in Gynaecology Department at Christian Medical College Hospital, Vellore, India over one year were recruited. This study was approved by the institutional review board and ethical committee of the hospital. Pre- and post-operative PVR were measured. The statistical analysis was done by using SPSS version 21 and P value < 0.05 was considered as statistically significant.Results: In this study 100 patients were recruited and 11% of women had pre-operative high post void residual volume of more than 100 ml. Stages of POP did not correlate with severity of LUTS and QOL. Pre-operative elevated PVR resolved post operatively in 91%, the P value <0.000 which was highly significant.Conclusions: 11% of women had preoperative high PVR. Stages of POP did not correlate with severity of lower urinary tract symptoms (LUTS) and quality of life(QOL). Pre-operative elevated PVR resolved post operatively in 91%, the P value < 0.000 which was highly significant. Majority of the patient with severe pelvic organ prolapse had elevated pre-op PVR which resolved post- operatively after surgical correction.
RESUMO
Precise measurement of postvoid residual (PVR) urine volume is a key factor in assessing patients with voiding dysfunction, including those with lower urinary tract problems. The safe and noninvasive ultrasound bladder scan is the preferred mode to measure PVR volume. However, this procedure has a false-positive rate up to 9%, in the presence of ovarian cysts, renal cysts, ascites, or uterine myoma with cystic degeneration. Until now, cystic lesions are known to cause false positivity in ultrasound bladder scanner. However, we encountered falsely-elevated PVR in two cases of non-cystic uterine myomas. We present these cases with detailed radiologic images and volume measurement data.

Background: Post Void Residual Urine (PVR) is a key marker for the evaluation of the efficacy of bladder emptying particularly in women with pelvic organ prolapse and lower urinary tract dysfunction. Objectives of the present study were to compare pre and postoperative post void residual urine volume and to know the relation of PVR to urinary symptoms and prolapse. Methods: 65 patients admitted with urogenital prolapse. Detailed history, general physical examination was done as per predesigned and pretested proforma. Grading for prolapse was done by POP-Q, Baden walker halfway. PVR was measured before and after operation Results: Age has shown significant relation with the raised PVR > 50 ml (p=0.007). Out of 65 cases, 11 had second, 48 had third degree and 6 had procedentia according to Baden Walker system. Urge and stress incontinence were complained by 43% and 26% of patients respectively and increased frequency and nocturia was complained by 68% and 65% of patients. Storage symptoms were not significantly associated with degree of prolapse or raised PVR. Straining to void, incomplete emptying and has to reduce to void were present in 42, 46 and 47 patients respectively and showed significant association with degree of prolapse. Except incomplete emptying other two were associated with raised PVR. Conclusion: Vaginal hysterectomy with anterior colporrhaphy was effective procedure in reducing elevated PVR in prolapse patients.
RESUMO
Objective To study the influence of post-void residual volume on prostate specific antigen (PSA) in patients with benign prostatic hyperplasia (BPH).Methods One hundred and sixty BPH patients who diagnosed by postoperative pathologic manifestations were selected.The patients were divided into 4 groups according to post-void residual volume with 40 cases each:non post-void residual volume (post-void residual volume ＜ 60 ml) group,less post-void residual volume (60 ml≤post-void residual volume ＜ 120 ml) group,middle post-void residual volume (120 ml ≤post-void residual volume ＜ 180 ml) group,mass post-void residual volume (post-void residual volume ≥180 ml) group.The serum PSA levels of 4 groups were observed.Results The PSA level in mass post-void residual volume group [(8.52 ± 6.72) iμ g/L] was significantly higher than that in non post-void residual volume group [(5.26 ± 4.16) μ g/L] and less post-void residual volume group [(5.93 ± 5.20) μ g/L],there were statistical differences (P ＜ 0.05),there was no statistical difference between non post-void residual volume group and less post-void residual volume group (P ＞ 0.05).Conclusions The serum PSA level in BPH patients with non post-void residual volume has no change,while the serum PSA level in BPH patients with mass post-void residual volume is significantly elevated.
RESUMO
As a standard method for the measurement of post-void residual urine volume, the urethral catheterization is commonly used. However, it is frequently associated with the discomfort of the patients, urethral trauma and urinary tract infection. A noninvasive method of determining the residual urine volume could minimize unnecessary catheterizations and be useful in the management of neurogenic bladder in the patient with spinal cord injury(SCI). This study was undertaken to evaluate the accuracy of a portable ultrasound scanner for measuring bladder volumes in SCI patients undergoing bladder training and to determine the factors affecting its accuracy. Sixty patients with SCI were included in this study. Two investigators performed the ultrasound measurement of the post-void residual urine volume alternately and the same procedures were repeated. After that, the urethral catheterization was done. In comparison of the residual volume measured by two different methods, the correlation coefficient(R2) of the two different methods was 0.996 and the mean value of difference between the residual volume measured by ulltrasound and by catheterization was 21.6 ml. The accuracy of the ultrasound measurements was not affected by gender, types of the neurogenic bladder, shape of the bladder, trabeculation of the bladder and central obesity. The results indicate that the portable ultrasound scanning method is a useful non-invasive method and can be substituted for the urethral catheterization in determination of bladder volumes in patients with SCI.
