[Diagnostic utility of cuff flowmetry in lower urinary tract obstruction in men].

OBJECTIVES PRIMARY OBJECTIVE: to investigate the usefulness of cuff flowmetry for the diagnosis of lower urinary tract obstruction in males. SECONDARY OBJECTIVES: 1) To investigate the relationship between isovolumetric pressure (Piso) and bladder contractility. 2) To investigate the relationship between the type of flow curves obtained by this method and the type of lower urinary tract obstruction, and previous history of prostate surgery. METHODS: We perform a cohort study in a series of 93 consecutive males (mean age 54.1 yr.) referred with functional lower urinary tract symptoms. They were interviewed about history of prostatic surgery, and they underwent isovolumetric pressure measurements (Piso), and corresponding flow (Qiso) by means of cuff flowmetry. From these parameters we calculated the Riso parameter, defined as Piso/(Qiso)2. A conventional pressure/flow study was performed afterwards, with computer calculation of urethral resistance parameters--footpoint and PURR curvature--, and the bladder contractility parameter Wmax. RESULTS: The diagnostic efficiency curve for the Riso parameter showed that the ideal cutpoint corresponded to a value of 1.29 cm H2O/(ml/sec)2. For this value the sensitivity for the diagnosis of lower urinary tract obstruction was lower than 78% and specificity was 73%. We elaborated a nomogram for the relationship between Piso and Qiso using a logistic regression model. This nomogram was divided in three areas (obstructive, equivocal, and not obstructive). If patients within the equivocal area (9.7% of the sample) were excluded, then the nomogram had a sensitivity of 84% and a specificity of 73% for the diagnosis of obstruction. We observed a significant association between flow curves with an absent initial peak morphology and obstruction of the constrictive type. No relationship was demonstrated between history of prostate surgery and type of curve. CONCLUSIONS: Cuff flowmetry has an acceptable sensitivity and specificity for the diagnosis of lower urinary tract obstruction. However, our study did not demonstrate its usefulness for the determination of the detrusor contractile capacity. Piso and Qiso parameters would be urethral resistance parameters.

[Penile fracture].

OBJECTIVES: Rupture of the corpora cavernosum is an uncommon pathology requiring immediate treatment. We performed a bibliographic search, and analyzed different diagnostic and therapeutic methods. METHODS/RESULTS: Two cases of traumatic rupture of the corpus cavernosum are described. The clinical features, penile ultrasound findings and immediate surgical treatment are discussed. CONCLUSIONS: Penile fracture is an uncommon pathology. Generally, history and physical examination are enough to establish the diagnosis. Penile ultrasound can help in case of doubt. Most urologists deem immediate surgery the standard therapy.

[Prospective study of the therapeutic usefulness and safety of a new disposable intraurethral occlusive device (Uriabsorber) for female stress urinary incontinence].

OBJECTIVES: To determine the therapeutic usefulness and side effects of a new disposable intraurethral device (Uriabsorber) for female stress urinary incontinence. METHODS: A prospective study was performed in a cohort of 48 women (mean age 42.7 yr.) consulting because of urinary incontinence with coughing. Lack of manual ability or difficulty to understand, pregnancy, puerperium, vaginitis, urinary tract infection and current administration of active treatment for urinary incontinence were all exclusion criteria. Patients were instructed about the use of the device. Two visits were performed: one after two weeks and the other at the end of the month. Clinical results were collected and urine analysis was performed. A multivariate statistical analysis was performed to determine what variables influenced the final result. RESULTS: Treatment withdrawal rate was 42% after one month, being most withdrawals before 14 days (19 cases, 40%). The causes of withdrawal were local discomfort (11 cases, 23%) and difficult insertion (3 cases, 6%). There were only five cases (10%) of urinary tract infection, and two cases (4%) of macroscopic hematuria. The presence of cystocele was associated with higher frequency of complications (80%). 79% of the patients completing the month of treatment had positive results (50% resolution of incontinence and 29% improvement). Multivariate statistical analysis showed that variables independently influencing the results were: incontinence intensity (the lower the intensity, the better the results), presence of urinary tract symptoms (the lower the intensity of the symptoms, the better the results), and absence of past history of pathology. CONCLUSIONS: The intraurethral disposable device significantly reduces the rate of urinary tract infections. Tolerance depends on the ability and motivation of the patients. It is indicated in the control of non intense urinary incontinence in motivated patients, without evident cystocele.
