[Atypical localization of a glomus tumor]. / Une tumeur glomique de localisation atypique.

Glomous tumors are rare and benign, generally affecting the fingers. Other localizations have nevertheless been described. We report the case of a patient who presented a supra-patellar glomous tumor provoking a pain-induced limp. Magnetic resonance imaging confirmed the diagnosis. The patient underwent complete surgical resection of the tumor followed by total resolution of the pain. Glomous tumors in an atypical localization may go unnoticed, with the risk of late or erroneous diagnosis. Symptoms are easily resolved with simple resection.

[Predictive value of the penile cuff-test for the assessment of bladder outlet obstruction in men]. / Valeur prédictive du cuff-test dans le diagnostic de l'obstruction sous-vésicale chez l'homme.

PURPOSE: To assess the diagnostic performances and the acceptability of the penile cuff test (PCT) which is a non invasive method for the evaluation of bladder outlet obstruction (BOO), in comparison with the pressure flow study (PFS), the actual gold-standard. MATERIAL: Monocentric prospective study comparing the following subsets: "obstructed", "not obstructed" or "equivocal", deduced from PFS vs PCT, in 30 consecutive patients presenting with lower urinary tract symptoms. For the PCT, a cuff placed around the penis inflated automatically during the micturition, until flow rate interruption. The interruption cuff pressure revealed the isovolumetric bladder pressure (Pcuff-int). The data collected - Pcuff-int and maximum flow rate - were automatically reported on ICS modified nomogram. RESULTS: With the PFS, 11 patients (39%) were classified "obstructed", six patients (22%) "non-obstructed" and 11 patients (39%) "equivocal". In 61% cases, the patient was classified in the same category by both techniques. The "obstructed positive predictive value" of the PCT was 82% and the "non-obstructed-equivocal negative predictive value" was 88%. The median acceptability visual analogic scale score was 1/10 (0-3) for the PCT whereas it was 5/10 (2-10) for the PFS. This difference was statistically significant (p=0.004). CONCLUSION: The PCT was a reliable non-invasive tool for the diagnosis of BOO in male, in comparison with PFS. The predictive values of the PCT were relevant and its tolerance was better than PFS.

[Self intermittent catheterization and voiding duration: in vitro flow rate assessment of catheters used in self-catheterization]. / Autosondages urinaires et temps de vidange : étude expérimentale de la vitesse de drainage des différentes sondes d'autocathétérisme.

OBJECTIVE: To assess the flow rate obtained by catheters used in self intermittent catheterization. MATERIAL: In vitro comparative study designed to compare the average flow rate obtained by intravesical catheters, by repeated flowmetric measures. The catheters studied were the most used in France in Fr10, 12 and 14 for female catheters and in Fr12, 14 and 16 for male catheters. RESULTS: We observed a strict relationship between Charriere and flow rate, both in female and male catheters These results were statistically significant (P<0.05). For female catheters, the average flow rate varied from 2.83 to 3.7 mL/s for Fr10 catheters, from 4.31 to 5.35 mL/s for Fr12 catheters and from 7.00 to 7.85 mL/s for Fr14 catheters (P<0.05). For male catheters, the average flow rate varied from 4.53 to 5.00 mL/s for Fr12 catheters, from 6.95 to 8.17 mL/s for Fr14 catheters and from 10.4 to 11.07 mL/s for Fr16 catheters (P<0.05). In female and male population, despite the observed flow rate differences between catheters, there were no statistically significant differences. CONCLUSION: This study demonstrated a better flow rate when Charriere increases. Thus, an objective adaptation of self catheterization's materiel is possible when the patient wishes to improve flow rate in order to reduce self intermittent catheterization duration.
