RESUMEN

AIMS: Ultrasound-estimated bladder weight (UEBW), is an emerging diagnostic tool, which has been used in both males and females with lower urinary tract dysfunction. The currently acknowledged UEBW calculation methods rely on the accurate measurement of bladder wall thickness (BWT). We aim to identify if subtle errors in BWT measurement have a significant impact on UEBW calculations. MATERIALS AND METHODS: Twenty patients were randomly selected from an overactive bladder patient cohort. The primary endpoint was to identify the range of false BWT measurements outside which significant changes in UEBW calculation occur. We used the Kojima method and a semi-automatic 3-D model that is based on Chalana's principle. Measurements were performed using the correct BWT and a series of faulty calculations from +0.5 mm to -0.5 mm using steps of 0.05 mm from true BWT. The effect of a fixed 0.5 mm BWT error was checked in bladder volumes above and below 250 ml and in three UEBW groups (<35 gr; 36-50 gr; >51gr). RESULTS: BWT measurement errors above 0.25 mm cause statistically significant changes in UEWB calculation when a 3-D model is used and errors above 0.15 mm when Kojima's method is used. At a fixed BWT error of 0.5 mm and bladder volume <250 ml, there is a 23.76% deviation from true UEBW, while at volumes >250 ml the deviation is 32.72%. The deviation is inversely proportional to the UEBW result, and heavier bladders deviate less. CONCLUSIONS: UEBW is a promising diagnostic tool, but small errors in BWT measurement might cause significant deviation from the true values. A 3-D calculation model appears to minimize such risks.

RESUMEN

PURPOSE: Pain rating scales are widely used for pain assessment. Nevertheless, a new tool is required for pain assessment needs in retrospective studies. METHODS: The postoperative pain episodes, during the first postoperative day, of three patient groups were analyzed. Each pain episode was assessed by a visual analog scale, numerical rating scale, verbal rating scale, and a new tool - pain point system scale (PPSS) - based on the analgesics administered. The type of analgesic was defined based on the authors' clinic protocol, patient comorbidities, pain assessment tool scores, and preadministered medications by an artificial neural network system. At each pain episode, each patient was asked to fill the three pain scales. Bartlett's test and Kaiser-Meyer-Olkin criterion were used to evaluate sample sufficiency. The proper scoring system was defined by varimax rotation. Spearman's and Pearson's coefficients assessed PPSS correlation to the known pain scales. RESULTS: A total of 262 pain episodes were evaluated in 124 patients. The PPSS scored one point for each dose of paracetamol, three points for each nonsteroidal antiinflammatory drug or codeine, and seven points for each dose of opioids. The correlation between the visual analog scale and PPSS was found to be strong and linear (rho: 0.715; P < 0.001 and Pearson: 0.631; P < 0.001). CONCLUSION: PPSS correlated well with the known pain scale and could be used safely in the evaluation of postoperative pain in retrospective studies.

RESUMEN

The purpose of this study is to present our experience with ureteral lithotripsy in ureteroscopy in children. Between 1996-2004, 105 patients aged 1,5-13 years with urolithiasis were treated in our department. Eight (8) of them with ureterolithiasis (5 in the lower ureter and 3 in the middle ureter) were treated with ureteroscopy (URS). The procedure was possible in all patients. The ureteroscopical approach of the stone and subsequent lithotripsy took place without major complications. There was a small difficulty to enter the ureteral orifice but it was overcome using dilations. On the other hand, there was no problem with the ureteral width. No stent was placed and all patients were stone free after 3 months. Ureteroscopy (URS) constitutes the golden standard for the treatment of ureteral lithiasis in children as well as in adults, as long as the narrow ureteral orifice is dilated with a guide wire. Pediatric ureter has good compliance and does not cause any problems to the whole procedure. The percentage of lithiasic children treated with open surgical procedures is less than 10% with a prospect for further reduction.

RESUMEN

PURPOSE: To describe the development and assess the outcome of a workshop on erectile dysfunction (ED) management based on participating physicians evaluations. METHOD: The study involved physicians who attended a workshop offered throughout the country, during a 3-year period. The workshop included tutorials, video-based dramatizations, and role-play sessions. A pilot study investigated the workshop's impact on physicians' attitudes toward patient-centeredness and sexual behavior issues; Patient-Practitioner Orientation Scale (PPOS) and Cross Cultural Attitude Scale (CCAS) were administered before and after the course. New knowledge acquisition, quality of presentation, and workshop's usefulness in their clinical practice were the dimensions used for workshop's evaluation. Analysis used quantitative and qualitative methods. RESULTS: A total of 194 questionnaires were administered during the pilot study and the response rate was 53.6%. A shift in attitudes toward patient-centeredness and less judgmental attitude toward patients' sexual attitudes were revealed (total PPOS score and Sharing subscale: P < 0.05, CCAS: P < 0.001). Six hundred physicians were asked to evaluate the workshops and the response rate was 62.3%. The tutorial session for "medical treatment of ED" (P < 0.001) and the role-play on sexual history taking (P < 0.05) received higher evaluation scores. Qualitative analysis showed that the most frequently reported category referred to the appropriateness of role-play as a teaching and awareness-raising technique (31.25%); a need for changes in clinical practice and communication patterns was identified by 20% of the participants who stressed the necessity for multidisciplinary approach, as well as the adoption of a nonjudgmental attitude toward patients. CONCLUSION: Training courses on ED management, using a combination of tutorial and interactive sessions, constitute an effective way of providing knowledge, enhancing physicians' communication skills with ED patients, and influencing attitudes toward patient-centeredness in sexual issues. Such results strongly support the establishment of sexual medicine courses at continuing medical education curricula.

RESUMEN

PURPOSE: We present 7 cases of arterial high flow priapism and propose management algorithms for the condition. MATERIALS AND METHODS: We studied 2 children and 5 adults with posttraumatic arterial priapism. Blood gas analysis and color Doppler ultrasonography of the corpora cavernosa confirmed the diagnosis in 4 adults, while 1 patient had already undergone cavernous artery ligation in elsewhere. In the children perineal compression resulted in detumescence, a sign that is proposed to be indicative of the diagnosis of arterial priapism (piesis sign) complementing physical examination. Mechanical compressive force was applied to the perineum of 1 boy, while the other received a watchful waiting program. All adults participated in an observation regimen except 1, who decided to undergo immediate embolization of the internal pudendal artery. RESULTS: Perineal compression led to the resolution of priapism in 1 child, while spontaneous resolution was noted in the other. An adult noticed spontaneous penile detumescence 3 to 4 months after trauma, which was attributable to site specific venous leakage and decreased, inflow in the contralateral cavernous artery. The patient underwent venous surgery and is on an intracavernous injection regimen. Successful embolization of the internal pudendal artery was performed immediately in 1 man and in the other 4 months after trauma due to social inconvenience. Adult patient 3 is still on the watchful waiting protocol (42 months), while the one who underwent cavernous artery ligation is receiving treatment for erectile dysfunction. CONCLUSIONS: Absent of long-term damaging effects of arterial priapism on erectile tissue combined with the possibility of spontaneous resolution or progressive concomitant hemodynamic abnormalities associated with blunt perineal trauma are suggestive of the introduction of an observation period in the management algorithm of high flow priapism. Such a period may help avoid unnecessary intervention and determine the impact of priapism on patient personal life. Perineal compression may be also added as part of the physical examination as a sign specifically indicative of arterial priapism.
