AbstractObjective: The aim of this study is to establish the importance of urodynamic investigations in women diagnosed with stress urinary incontinence (SUI) who have indication of surgical treatment.Methods: We performed a retrospective study over a period of 3 years (January 2012-December 2014) in Clinic of Urology from Tirgu Mures. The inclusion criteria were: female patients diagnosed with SUI having indication of surgical treatment and the existence of urodynamic investigations (uroflowmetry and pressure-flow study). We evaluated 118 patients with SUI. From this patients, 24 cases (20.3%) accomplished the criteria from above.Results: We included in this study 24 patients aged 64.25+/−8.25 (standard deviation). Pressure-flow study revealed an impaired detrusor contraction in 13 cases. Statistical anaysis pouved a relation between existence of post void residual urine (PVR) and underactive detrusor (UD) (p=0.01). There is no correlation between maximum flow rate (Qmax) and UD, r=0.18 (CI= −0.2-0.5), p=0.3 and between normal value of Qmax and normal detrusor pressure (Pdet), r= 0,28(CI=−0.6-0.8), p=0.58. Also there is no relation between a low Qmax and UD, p=0,5. There is a statistical relation between increased abdominal pressure (Pabd) and UD, p=0.02.Conclusions: Uroflowmetry has the role to guide us concerning the micturition process Pressure-flow study is indicated in management of SUI, in selected cases, in patients with voiding symptomatology, the suspicion of a detrusor contractility dysfunction, abnormal uroflowmetry results, existence of PVR, in prediction of the surgical treatment outcome or if we think that the findings can change the choice of treatment.

Introduction: Urinary retention can be either chronic or acute in onset. Urinary retention can result from impaired detrusor contractility or obstruction of bladder outlet. Twenty five to 30% of men with decreased flow are not obstructed 1. Either uroflowmetry or post-void residue (PVR) can not differentiate obstruction from impaired detrusor contractility. In this study, an effort has been paid to know the usefulness of pressure-flow study in urinary retention due to suspected benign prostatic hyperplasia(BPH) cases for predicting the outcome of surgery. Methods: This is a before after clinical study, conducted in Bangabandhu Sheikh Mujib Medical University, Dhaka. Total 32 patients were selected for the study. Patients age ranges from 49-78 years.Patients with chronic and refractory urinary retention due to BPH were enrolled for the study. They were divided into group A (pre-operative) and group B (Post-operative). TURP was done in all 32 patients by single surgeon. Study variables were detrusor pressure at maximum flow (Pdet@Qmax), bladder outlet obstruction index(BOOI), bladder contractility index( BCI) and post void residue (PVR). Result: Total number of patients was 32. Age ranges from 49-78 years. Twenty one (65.6%) had BPH with chronic retention and 11 (34.4%) had BPH with refractory retention.Pdet@Qmax between Group A and Group B was highly significant (p=0.001). But difference is not significant in Pdet@Qmax d” 40 subgroup of patients (p=0.673). Bladder outlet obstruction index between Group A and Group B is highly significantly (p=0.001), but, that does not observed in BOOI <20 subgroup(p=0.600). Bladder contractility index in both Normal (BCI 100-150) and strong ( BCI >150 ) subgroups are significant ( p=0.001 and 0.001 respectively ). But it is not significant in BCI<100 sub group (p=0.021). Post void residue between Group A and Group B is highly significant (p=0.001). But in PVR >300m subgroup, difference is insignificant (p=0.120). Conclusion: In this study, overall favorable outcome observed in all patients after TURP but Pdet@Qmax <40 cm of water, BOOI <20, BCI <100 and PVR >300 ml groups of patients are at high risk of unfavorable clinical outcome after TURP. With the help of presence flow study (PFS) prior knowledge of these factors, it is possible to predict postoperative outcome. Bangladesh Journal of Urology, Vol. 19, No. 2, July 2016 p.74-77

Many parameters are available for evaluating patients with benign prostatic hypertrophy (BPH) in order to assess the necessity for treatment and to evaluate results. At present there is no real agreement on their order of importance. This paper tries to define from a theoretical and practical point of view the role of the following parameters: symptoms; symptom scores; visual scores; time/voided volume chart; prostate size; uroflowmetry, nomograms for flow; residual urine; pressure/flow study; mathematical and computer processing of pressure/flow study. The Author underlines the critical role of invasive urodynamics (pressure/flow study) in categorizing patients as obstructed or non-obstructed, in grading the severity of outflow obstruction and in evaluating the pattern of detrusor contractility. Present studies to evaluate the results of old and recent treatments should include invasive urodynamics in order to obtain homogeneous groups of patients and to overcome the prevailing empiricism.

Purpose. In women who reported a weak urinary stream, the efficacy of treatment chosen according to the urodynamic findings on pressure-flow study was prospectively evaluated.Materials and Methods. Twelve female patients with maximum flow rates of 10 mL/sec or lower were analyzed in the present study. At baseline, all underwent pressure-flow study to determine the degree of bladder outlet obstruction (BOO) and status of detrusor contractility on Schäfer's diagram. Distigmine bromide, 10 mg/d, was given to the patients with detrusor underactivity (DUA) defined as weak/very weak contractility, whereas urethral dilatation was performed using a metal sound for those with BOO (linear passive urethral resistance relation 2–6). Treatment efficacy was evaluated using the International Prostate Symptom Score (IPSS), uroflowmetry, and measurement of postvoid residual urine volume. Some patients underwent pressure-flow study after treatment.Results. Urethral dilatation was performed for six patients with BOO, while distigmine bromide was given to the remaining six showing DUA without BOO. IPSS, QOL index, and the urinary flow rate were significantly improved in both groups after treatment. All four of the patients with BOO and one of the three with DUA but no BOO who underwent pressure-flow study after treatment showed decreased degrees of BOO and increased detrusor contractility, respectively.Conclusions. Both BOO and DUA cause a decreased urinary flow rate in women. In the short-term, urethral dilatation and distigmine bromide are efficacious for female patients with BOO and those with DUA, respectively.

Background: Stress urinary incontinence (SUI) is the complaint of involuntary leakage of urine during increased abdominal pressure in the absence of detrusor contraction. Although not a life-threatening condition, stress urinary incontinence causes various physical, psychological, and sexual problems for millions of women and their families. Although these conditions are highly prevalent, they are not often reported by patients. This was the reason for the study; to find out the prevalence and the associated risk factors.Methods: A total of 400 patients presenting in the gynaecology outpatient department with various complaints were studied. A detailed history was taken, and examination was done. Urine microscopy and culture studies were done and whenever found positive; the infection was treated. Bonney’s test was done on full bladder.Results: Stress urinary incontinence was diagnosed in 41 (10.30%) of the women. The most common co morbidity was found to be tuberculosis and other lung diseases. Among the study population, 4% of women had culture positive urinary tract infection.Conclusions: Stress urinary incontinence was seen in 10.30% of the study population. It was seen more commonly among the elderly. Urine routine and microscopy was done for all patients complaining of leakage of urine or any other urinary complaints.
