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.

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.

The Authors report their experience on 24 patients with prostatodynia. The Adynamic alterations, which occur in most cases, show the usefulness of cystomanometry and pressure-flow study for providing a better nosological picture and therapeutic management.

Previous experiments from this laboratory indicated that normal kidneys may not have significant intrinsic ability to autoregulate their blood flow when renal arterial pressure is varied. However, in these earlier studies, the renal blood flow was less than that generally accepted as normal, and there was a possibility that the renal circulation had not been completely isolated. This could have resulted in extrarenal blood flow during the pressure-flow study. In the present experiments, renal blood flows were in the normal range at all pressure levels. This difference was achieved by rendering the animals areflex prior to the laparotomy. The pressure-flow relationship was studied under these conditions, and the resulting curves were slightly concave to the pressure axis in the lower pressure range, indicating only a mild degree of autoregulation, approximately the same degree as that found in other tissues. However, the renal blood flow still increased rapidly with each increase in perfusion pressure even in the range of so-called autoregulation. It was also shown that all the blood that passed through the perfusion system also passed through the kidney, eliminating the possibility of extrarenal blood flow.
