“…Some au thors consider the variations as physiological or artificial without any pathological significance [1]; others de scribed it as a pathological entity connected mainly to sen sorio urge [2]; still others describe various types [3,4] with or without pathological implications.…”

From an analysis of 202 patients and a careful literature analysis we conclude that pathological urethral instability should be differentiated from physiological urethral pressure variations by the following criteria: a pronounced amplitude of at least one third of the maximum urethral pressure variations by the following criteria: a pronounced amplitude of at least one third of the maximum urethral closure pressure (usually > 25 cm H₂O), a short duration (1–5 s), a simultaneous inhibition of the electromyographic activity in urethral and (or) anal sphincter, and the occurrence of the phenomena starting at the beginning of bladder filling (100 ml).

“…2,11 In clinical practice, however, the reported e ects of estrogen treatment, in terms of cure rates and urethral pro®le measurements, are con¯icting. 3,4,12,13 These aspects con®rm, as is known, that UPP is of limited practical value in studying continence or in the follow-up of incontinent patients undergoing estrogen therapy.…”

“…Images obtained from each subject were independently examined by two sonographers who were blind to the subject's clinical status and age. The sonographers were asked to give a subjective score of the degree of vascularization along the entire urethra as follows: (a) minimal or absent (1), (b) poor (2), (c) moderate (3), (d) good (4). We compared the values of the maximum closure urethral pressure (MCUP), performed by microtransducers, of each pathologic patient with the ultrasound score.…”

The feasibility of urethral color ultrasound imaging in the diagnosis of female intrinsic sphincter deficiency: preliminary results

Study design: Prospective study. Objectives: To evaluate the feasibility of color ultrasound imaging of the urethra in association with UPP to diagnose intrinsic sphincter de®ciency (ISD). Setting: Italy. Methods: We studied a group of 13 normal female volunteers (mean age 29 years) during the estrogenic phase and a group of 15 patients (mean age 63.9 years) with ISD. All patients and normal volunteers underwent color ultrasound imaging using a 4 ± 7 MHz convex broad band transducer. Translabial sagittal scans of the urethra were obtained. The color ultrasound parameters were optimized for detection of parenchymal slow¯ows. A subjective score of the degree of vascularization along the entire urethra was established as follows: (a) minimal or absent (1), (b) poor (2), (c) moderate (3), (d) good (4). Statistical analysis, using the nonparametric Mann-Whitney rank sum test, was carried out to determine di erences of ultrasound scores between volunteers and patients. Results: The statistical evaluation showed that the di erences between the ultrasound scores in the two groups was statistically signi®cant (P50.001). Conclusion: We a rm that color ultrasound imaging of the urethra seems to be feasible and useful in association with UPP in the diagnosis of ISD even if this echographic investigation needs further observations.

“…Chez la femme non ménopau-sée, non incontinente à l'effort, la pression urétrale augmente au fur et à mesure du remplissage vésical. Cette augmentation n'est pas retrouvée chez la femme incontinente à l'effort [37][38][39][40].…”

“…Cet engouement pour le concept « d'instabilité urétrale » a trouvé peu d'écho au-delà des années 1980. Sorensen [39] a montré qu'il existait des variations physiologiques de la pression urétrale atteignant parfois plusieurs dizaines de centimètres d'eau. Les artéfacts techniques liés au déplacement de la sonde ou de la patiente peuvent aussi simuler une instabilité urétrale.…”

Les fonctions urétrales peuvent être explorées par le Valsalva Leak Point Pressure et la mesure des pressions urétrales en profilométrie. Ces tests peuvent avoir un apport intéressant dans le diagnostic et l'évaluation pronostique préopératoire des incontinences urinaires à l'effort de la femme. Mots clés : Incontinence urinaire d'effort -Valsalva leak point -SphinctérométrieAbstract: Urethral function can be evaluated using Valsalva leak point pressure and sphincterometry. These assessments can help in diagnosing and determining a prognosis for urinary stress incontinence, especially before surgical intervention.
