A national survey of lower urinary tract symptoms in Jordan.

Objective: To determine the prevalence of lower urinary tract symptoms (LUTS) and their severity population in Jordan. Methods: This cross-sectional survey was conducted using a paper-based survey between August and September in 2019. The study was carried out in the health care centers or hospitals in three different regions of Jordan: North (Irbid and Jarash), Middle (Amman, Madaba, Salt, and Zarqa), and South (Karak and Aqaba). Results: To estimate the prevalence of LUTS, two definitions were used, including the first definition (presence of any LUTS regardless of the degree of severity) and the second definition (presence of any LUTS that occurs half the time or more). According to the first definition, 1038 (89.9%) reported LUTS (male: 47.3%, female: 52.7%), while 763 (66.1%) reported LUTS according to the second definition (male: 45.6%, female: 54.4%). According to the International Prostate Symptom Score characterization, 73.9% had nocturia and 62.9% reported daytime increased frequency. Conclusion: LUTS are highly prevalent among the Jordanian population, and more than half of them have nocturia or daytime increased frequency as most frequently reported symptoms.

Frank haematuria secondary to ruptured pseudoaneurysm of the inferior vesical artery: a case report and review of the literature.

BACKGROUND: Pseudoaneurysm of a vesical artery is an extremely rare iatrogenic complication; however, it may cause fatal haematuria. CASE PRESENTATION: A 21-year-old Arab Jordanian male had multiple optical urethrotomies for an iatrogenic urethral stricture after he had rectal surgery for Hirschsprung's disease at the age of 2 years. During one of his admissions to the Emergency Room (ER) with urinary retention, an attempt at suprapubic catheter insertion was complicated by massive bleeding at the insertion site of the catheter. Abdominal exploration showed a distended urinary bladder with clots and bleeding seen at the bladder neck that was controlled with multiple sutures. The patient rebled again two times; the first was controlled with cystoscopy and cautery for a pulsatile bleeder seen at the bladder neck. The second time, the patient required blood transfusion of three units of packed red blood cells. Angiography was performed, and a pseudoaneurysm at the base of the urinary bladder from the inferior vesical artery was diagnosed, which was controlled by embolization. CONCLUSION: Pulsatile bladder haemorrhage following urological intervention is suggestive of pseudoaneurysm or arteriovesical fistula, and angiography with embolization is recommended.

Validating 7-items Overactive Bladder Symptom Score (OABSS) through Arabic linguistic version.

The scoring of the 7-item Overactive Bladder Symptom Score (OABSS) questionnaire is unusual because its scale varies with the same maximum and minimum scoring values and quantifies all aspects of OAB. The questionnaire also contains a graded response for urgency. The current study is mainly concerned with the development and validation of the OABSS questionnaire for Jordanian patients. The process of translating the English OABSS questionnaire into the Arabic language involved forward and backward translations. Afterward, a prospective study was conducted to validate the Arabic version of the OABSS questionnaire by examining 235 patients from the outpatient clinics of Karak Governorate Teaching Hospital. The Arabic OABSS questionnaire was completed by all the enrolled patients before and after three months of treatment with solifenacin 5 mg taken once daily. The study included 235 regular patients (152 females and 83 males) diagnosed with OAB in accordance with the definition of the International Continence Society (ICS). The results showed major and significant differences on all seven domains of the questions on the OABSS questionnaire before and after receiving treatment (p < 0.05). Confirmatory Factor Analysis was used to measure the reliability and the questionnaire was found to be highly reliable for the construct variables. The findings derived from the current study would be beneficial for local urologists and researchers, as the Arabic version of the OABSS questionnaire was proven to be a reliable instrument for use in the assessment of OAB. Future studies are needed to compare different translated questionnaires relating to OAB.Trial registration number: NCT04309890.

Mejora de las variaciones en la ecografía vesical Evaluación del volumen de orina residual posmiccional en obstrucción moderada de la salida de la vejiga / Improving Variations in Bladder Ultrasound Assessment of Post-Void Residual Urine Volume in Moderate Bladder Outlet Obstruction

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.

The Prevalence of Detrusor Underactivity and its Symptoms Co-relation with Urodynamic Study Findings in Patients with Lower Urinary Tract Symptoms.

PURPOSE: This study determines the prevalence and clinical presentation of detrusor underactivity (DU) and its urodynamic characteristics in adult patients with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: This retrospective study has reviewed the symptoms and urodynamic study (UDS) findings of 283 patients with LUTS. Chi-square analysis was used to present the prevalence of UDS characteristics in both sexes. RESULTS: Out of records of 206 patients included in this study, fifty-one (24.76%) patients were diagnosed with DU based on bladder contractility index. Storage lower urinary tract symptoms were the most prevalent characteristic presentation in both sexes as compared to the difficulty in voiding, recurrent urine retention, and urinary incontinence. Bladder outlet, sphincter EMG findings, and degree of DU were significantly correlated with gender. CONCLUSION: DU is a prevalent and sophisticated bladder pathology rather than a simple one. It requires more attention from the urologists, and evaluations, including UDS, to differentiate it from other pathologies.

Urological Aspects in Patients with Alkaptonuria: A Case-Control Study.

This study aimed to evaluate the urinary tract for dynamic function and stones and calcifications in patients with alkaptonuria. Thirty-eight patients were prospectively divided into two groups. Study group (A) involved 17 patients; the average age was 42 years. The control group (B) involved 21 patients; the average age was 37 years. All patients from the two groups underwent uroflowmetry assessment and ultrasonography for the kidneys and urinary bladder, and prostate in two phases (full bladder and empty bladder). Group A-Bladder volume ranged between 400 and 520 cc. The peak flow rate was between 7 and 23 mL/s, with an average of 18.6 mL/s. Flow rate curves shape were acceptable to the normal bell-shape curve in 11 patients. Seven patients (41%) had prostate calcification accounting for 5%-35% of prostate size. Group B-Bladder volume ranged between 290 and 510 cc. The peak flow rate was 8-27 ml/s, with an average of 20 mL/sec. Normal bell shape voiding curves were observed in 17 patients (80%). Four patients (19%) had prostate calcification accounting for 2%-12% of prostate size. Renal measurements on ultrasonography were the same in both groups. Patients with alkaptonuria developed prostate calcification at younger age; they have a slight but not statistically significant reduced peak urinary flow rate and post void residual urine.

Complete Urethral Duplication: Case Report and Literature Review.

Urethral duplication (UD) is a rare-congenital anomaly that can affect the genito-urinary system. The aim of this case report is to show our experience in this case, including the investigation and operative techniques that we utilized. In the literature review, we will show that different types of duplication, radiological investigations, and surgical techniques have been used to treat this condition.

Distal hypospadias repair with or without foreskin reconstruction: A single-surgeon experience.

OBJECTIVE: Dartos flap coverage is routinely used as a protective layer during tubularized incised plate urethroplasty (TIPU) except when an associated foreskin reconstruction (FSR) precludes its use. In this study we compare the outcome of distal hypospadias repair with and without foreskin reconstruction by the same surgeon. MATERIALS AND METHODS: Between September 2002 and June 2007, 215 children with distal hypospadias underwent stented TIPU by a single surgeon. Of these, 25 (glanular 8, coronal 17) underwent a two-layer FSR without dartos flap coverage. An age- and time-matched group of 49 patients (glanular 10, coronal 39) who underwent TIPU with dartos flap coverage without foreskin reconstruction (NoFSR) were selected for comparison. Operative time and complications were recorded. RESULTS: There was no significant difference in severity of hypospadias and follow-up duration (mean 17 vs 19 months, P=0.57) between the two groups. Operative time ranged between 30 and 86min (mean 57) in the FSR group and 35 and 113min (mean 75) in the NoFSR group (P

Learning from the learning curve: factors associated with successful endoscopic correction of vesicoureteral reflux using dextranomer/hyaluronic acid copolymer.

PURPOSE: Conflicting reports exist regarding the parameters guiding successful correction of vesicoureteral reflux using dextranomer/hyaluronic acid copolymer. We performed logistic regression analysis to evaluate the effect of injected volume while adjusting for other factors potentially associated with success following dextranomer/hyaluronic acid copolymer injection. MATERIALS AND METHODS: Between July 2003 and June 2006, 126 consecutive patients (34 boys and 92 girls) with a mean +/- SD age of 6.5 +/- 3.7 years with primary vesicoureteral reflux (196 refluxing ureters) underwent injection for febrile urinary tract infections. Success was defined as complete reflux resolution. Age, gender, laterality, preoperative vesicoureteral reflux grade, surgeon experience, dextranomer/hyaluronic acid copolymer volume, time to surgery from initial presentation and preoperative treatment for lower urinary tract symptoms were analyzed. RESULTS: Vesicoureteral reflux grade was I to V in 7 (3.5%), 53 (27%), 91 (46.4%), 30 (15.3%) and 15 renal units (7.6%), respectively. The success rate after 1 injection was 50% by patient and 59.2% by ureter. Mean injected volume was 0.9 +/- 0.27 ml in those who had a successful injection vs 0.67 +/- 0.24 ml in those in whom injection failed (p <0.001). The success rate after 1 injection was 78.9% using 0.8 ml or greater dextranomer/hyaluronic acid copolymer compared to 31.7% with less than 0.8 ml. Multivariate analysis confirmed that higher dextranomer/hyaluronic acid copolymer volume (p = 0.001), lower preoperative grade (p = 0.013), surgeon experience (p = 0.025) and treatment for lower urinary tract symptoms (p = 0.009) were associated with successful correction of vesicoureteral reflux. CONCLUSIONS: Our analysis strengthens the previously reported association of surgeon experience and vesicoureteral reflux grade with successful endoscopic vesicoureteral reflux correction. The data also revealed an association between injected volume and vesicoureteral reflux correction even while controlling for other variables, highlighting its importance as a true success modifier.

Feasibility study of a novel urinary bladder bioreactor.

We have devised a bioreactor to simulate normal urinary bladder dynamics. The design permits a cell-seeded scaffold made from a modified porcine acellular matrix to be placed between 2 closed chambers filled with culture medium and be mechanically stimulated in a physiologically relevant manner. Specifically designed software increased hydrostatic pressure from 0 to 10 cm of water in a linear fashion in 1 chamber, resulting in mechanical stretch and strain on the scaffold. Pressure was increased over 55 min (filling) and then decreased to 0 over 10 s (voiding). Commercially available small intestinal submucosa scaffolds were used to test the mechanical capabilities of the bioreactor, and pressure waveforms were generated for up to 18 h. Scaffolds were seeded with bladder smooth muscle or urothelial cells and incubated in the bioreactor, which generated pressure waveforms for 6 h. Scaffold integrity was preserved as seen through Masson's trichrome staining. No obvious contamination of the system was noted. Hematoxylin and eosin staining showed presence of cells after incubation in the bioreactor, and immunohistochemistry and real-time reverse transcriptase polymerase chain reaction suggested continued cellular activity. Cellular orientation tended to be perpendicular to the applied pressure. Preliminary results suggest that our bioreactor is a suitable model for simulating normal physiological conditions of bladder cycling in an ex vivo system.
