Abstract
PURPOSE OF REVIEW Uroflowmetry is widely used for initial non-invasive evaluation of lower urinary tract disorders. Current clinical use is mostly restricted to a scrutiny of the maximum flow rate and uroflow pattern recorded by a conventional flowmeter in a health care facility. There are several advancements in our understanding and in available technologies that promise to transform clinical utilization of this simple test. RECENT FINDINGS Several aspects of the uroflow test in addition to maximum flow rate and uroflow pattern show potential diagnostic utility. This includes flow acceleration, uroflow indices, uroflow-electromyography including lag time, stop uroflow test, and uroflow-based nomograms. There are initial attempts to use artificial intelligence in analysis. There is also new data with regard to factors influencing variability of uroflow testing that might influence the diagnostic value in as yet uncertain ways including diurnal variability, postural variability, locational variability, and operator variability. There are new technologies for uroflow testing in a home environment allowing for easy repetition. However, there are several challenges owing to a paucity of clinical data and standardization. There are also critical lacunae in terminology that need to be addressed. There are exciting new advancements in the field of uroflowmetry. However, there is need to standardize and validate the newer uroflow tracing analyses and technologies.

Urinary continence after high urogenital sinus repair conducted with posterior prone approach: electromyography-uroflowmetric assessment. Int Urol Nephrol 2021; 53:1813-1818. [PMID: 34037908 DOI: 10.1007/s11255-021-02895-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Accepted: 05/22/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE We aimed to present the results of urinary continence assessment objectively with electromyography (EMG)-uroflowmetry after high urogenital sinus (HUGS) repair with posterior prone approach without division of rectum. METHODS The records of patients who underwent HUGS repair via posterior prone approach between January 2005 and July 2018 were reviewed retrospectively. Incontinence, dysuria, hesitation, and straining during urination were evaluated during the clinical follow-up. Dysfunctional voiding scoring system was used as a questionnaire. Patients were re-evaluated with EMG-uroflowmetry in terms of voiding volume and pattern, voiding time, maximum flow rate, average flow rate, maximum flow time, and post-voiding residual volume. RESULTS Seven patients with HUGS were treated with a posterior prone approach. The median age of the patients was 18 months (8-21 months). The median UGS length was 4.4 cm (3.6-5.5 cm), urethral length was 1.1 cm (1.0-1.5 cm), and vaginal length was 4.9 cm (4.1-5.1 cm). No urination or defecation problems were described by the patients or their parents. When the results of the dysfunctional voiding scoring systems questionnaire were analyzed, results scored 7 (range 5-8). EMG-uroflowmetric test graphics of the patients showed normal flow curves without plateau, intermittency or irregularity. Pelvic EMG assessment was normal in all patients. CONCLUSION EMG-uroflowmetry has shown objectively that urinary continence and normal voiding pattern are preserved after HUGS repair with posterior prone approach without division of rectum.
