OBJETIVO: estudar, por meio da ultrassonografia perineal, as modificações da junção uretrovesical (JUV) e da uretra proximal (UP) promovidas pela cirurgia combinada de Marshall-Marchetti-Krantz-Burch (MMK-B). MÉTODOS: foi realizado um estudo de intervenção longitudinal e prospectivo. Trinta e duas mulheres com incontinência urinária de esforço foram submetidas à ultrassonografia perineal antes e 30 dias depois da cirurgia para avaliar a distância pubo-uretral (DPU), o comprimento da uretra proximal (UP), a distância horizontal da JUV (DHJUV) e a distância vertical da JUV (DVJUV), estando a paciente em repouso, e os seus deslocamentos durante a manobra de Valsalva. Os resultados foram expressos em médias e desvios padrão. Para a comparação dos resultados do pré aos do pós-operatório, foi usado o teste t de Student para amostra pareada quando as variáveis cumpriam os critérios do teste de normalidade, e o teste pareado de Wilcoxon quando não cumpriam. RESULTADOS: em comparação às medidas do pré-operatório, a cirurgia de Marshall-Marchetti-Krantz-Burch reduziu a DPU no repouso (13,4 mm x 10,2 mm) e no esforço (19,8 mm x 9 mm); reduziu a DHJUV no repouso (14 mm x 4,3 mm) e no esforço (20,8 mm x 6,4 mm); aumentou o comprimento da UP no repouso (16,7 mm x 19,7 mm) e no esforço (1,6 mm x 15,4 mm); aumentou a DVJUV no esforço (-5,4 mm x 14,8 mm). A cirurgia de MMK-B não alterou a DVJUV no repouso (16,2 mm x 18,7mm, p=0,085). CONCLUSÕES: a cirurgia de Marshall-Marchetti-Krantz-Burch reduziu significativamente a mobilidade vertical e horizontal da junção uretrovesical, porém sem elevar a junção uretrovesical. PURPOSE: to study the changes in the urethrovesical junction (UVJ) and in the proximal urethra (PU) caused by the Marshall-Marchetti-Krantz-Burch (MMK-B) combined surgery through perineal ultrasonography. METHODS: an interventional, longitudinal and prospective study has been conducted. Thirty-two women with stress urinary incontinence were submitted to perineal ultrasonography before and 30 days after surgery to evaluate the pubo-urethral distance (PUD), the proximal urethra length, the UVJ horizontal distance (UVJHD) and the UVJ vertical distance (UVJVD), the patient being at rest, and in effort during the Valsava manoeuvre. Results have been expressed in mean and standard deviation. The Student's t-test has been used to compare pre and postoperative results whenever the variables fulfilled the normality test criterion; otherwise, the Wilcoxon's paired test has been used. RESULTS: as compared with the preoperative measures, the Marshall-Marchetti-Krantz-Burch surgery has reduced the PUD at rest (14 mm x 4.3 mm) and during effort (20.8 mm x 6.4 mm); has reduced the UVJHD at rest (14 mm x 4.3 mm) and during effort (20.8 mm x 6.4 mm); has increased the PU length at rest (16.7 mm x 19.7 mm) and during effort (1.6 mm x 15.4 mm); and has increased UVJVD during effort (-5.4 mm x 14.8 mm), but has not changed it at rest (16.2 mm x 18.7 mm, p = 0.085). CONCLUSIONS: the Marshall-Marchetti-Krantz-Burch surgery has significantly reduced the urethrovesical junction vertical and horizontal mobility without raising the urethrovesical junction.

OBJETIVO: Comparar parâmetros ultrassonográficos relacionados à junção uretrovesical e uretra proximal em pacientes curadas e não curadas, tratadas cirurgicamente pela técnica de Burch, com a finalidade de estabelecer se há correspondência com fatores prognósticos. MATERIAIS E MÉTODOS: Trinta pacientes foram selecionadas e divididas em dois grupos: 15 consideradas clinicamente curadas e 15 consideradas não curadas. As pacientes foram submetidas a ultrassonografia transvulvar no pré-operatório e aos 30 e 180 dias do pós-operatório. RESULTADOS: No pré-operatório, o deslocamento da uretra proximal foi maior nas pacientes curadas (15,87 ± 4,55 mm × 12,47 ± 3,52 mm - p < 0,05). No pós-operatório, no esforço, a distância vertical da junção uretrovesical e a uretra proximal foram maiores nas pacientes curadas (12,87 ± 5,80 mm × 5,13 ± 6,55 mm - p < 0,01; e 13,07 ± 6,44 mm × 6,20 ± 6,14 mm - p < 0,01), e o deslocamento vertical da junção uretrovesical e da uretra proximal foi maior nas pacientes não curadas (8,47 ± 3,98 mm × 5,13 ± 2,36 mm - p < 0,001; e 8,33 ± 4,54 mm × 5,20 ± 2,90 mm - p < 0,05). CONCLUSÃO: A ultrassonografia da junção uretrovesical e da uretra proximal pode ser considerada como um método eficaz de avaliação dos parâmetros prognósticos do tratamento cirúrgico de mulheres com incontinência urinária de esforço.OBJECTIVE: To compare sonographic parameters related to the urethrovesical junction and proximal urethra in cured and not cured patients surgically treated with the Burch technique, for establishing a possible correlation with prognostic factors. MATERIALS AND METHODS: Thirty female patients were selected and divided into two groups: 15 patients considered as clinically cured and 15 not cured. The patients were submitted to preoperative transvulvar ultrasonography, with the examination being repeated at the 30th and 180th postoperative days. RESULTS: At the preoperative examination, the proximal urethra displacement was largest in the cured patients (15.87 ± 4.55 mm × 12.47 ± 3.52 mm - p < 0.05). At the postoperative examination, with strain, the vertical distance of the urethrovesical junction and the proximal urethra were largest in the cured patients (12.87 ± 5.80 mm × 5.13 ± 6.55 mm - p < 0.01; and 13.07 ± 6.44 mm × 6.20 ± 6.14 mm - p < 0.01), and the vertical displacement of the urethrovesical junction and proximal urethra was largest in the not cured patients (8.47 ± 3.98 mm × 5.13 ± 2.36 mm - p < 0.001; and 8.33 ± 4.54 mm × 5.20 ± 2.90 mm - p < 0.05). CONCLUSION: Ultrasonography of the urethrovesical junction and proximal urethra can be considered as an effective method for evaluating prognostic parameters in the surgical management of women with stress urinary incontinence.

OBJETIVO: Descrever a importância da ultra-sonografia transvulvar na avaliação das diferenças anatômicas induzidas pelas cirurgias de sling de fáscia lata e tension-free vaginal tape. MATERIAIS E MÉTODOS: Quarenta mulheres com incontinência urinária de esforço, com idades entre 30 e 60 anos, foram tratadas por sling de fáscia lata (20 pacientes) ou tension-free vaginal tape (20 pacientes). A ultra-sonografia transvulvar da junção uretrovesical e da uretra proximal foi a principal ferramenta de investigação pré- e pós-operatória. Os parâmetros estudados foram: distância vertical e distância horizontal da junção uretrovesical, distância pubouretral e comprimento da uretra proximal. RESULTADOS: A distância vertical da junção uretrovesical não variou significativamente após a sling de fáscia lata (p > 0,10). A distância pubouretral e a uretra proximal tornaram-se menores (p < 0,003) e a distância horizontal da junção uretrovesical tornou-se menor só no repouso (p = 0,03) após a sling de fáscia lata. A tension-free vaginal tape diminuiu o deslocamento vertical da junção uretrovesical (p = 0,0005) e o comprimento da uretra proximal (p = 0,02). CONCLUSÃO: A ultra-sonografia transvulvar foi fundamental para documentar que as cirurgias de sling de fáscia lata e tension-free vaginal tape alongam a uretra proximal, sendo a sling de fáscia lata de forma mais eficaz. A sling de fáscia lata enfoca a diminuição da distância pubouretral e a tension-free vaginal tape, o deslocamento vertical da junção uretrovesical.OBJECTIVE: The aim of this study was to describe the role of transvulvar ultrasonography in the assessment of anatomical changes following fascia lata sling or tension-free vaginal tape procedures. MATERIALS AND METHODS: Forty women in the age range between 30 and 60 years had fascia lata sling (20 patients) or tension-free vaginal tape (20 patients) placement for treating stress urinary incontinence. Transvulvar ultrasonography was utilized, both pre- and post-operatively, as the main investigational tool in these cases for evaluating the urethrovesical junction vertical and horizontal distances, pubo-urethral distance and proximal urethra length. RESULTS: The urethrovesical junction vertical distance did not vary significantly after the fascia lata sling surgery (p > 0.10). Both the pubo-urethral distance and the proximal urethra length became shorter (p < 0.003), and the urethrovesical junction horizontal distance was reduced only at rest (p = 0.03). The tension-free vaginal tape procedure resulted in a reduction of the urethrovesical junction vertical distance (p = 0.0005) and of the proximal urethra length (p = 0.02). CONCLUSION: Transvulvar ultrasonography was of utmost importance in the demonstration that both the fascia lata sling and tension-free vaginal tape surgical procedures elongate the proximal urethra, even though the fascia lata sling technique does it more effectively. The fascia lata sling technique is more focused on shortening the pubo-urethral distance, and the tension-free vaginal tape, on the correction of the vertical displacement of the urethrovesical junction.

OBJETIVO: Determinar a influência da aferição da pressão intra-abdominal na avaliação ultra-sonográfica da junção uretrovesical (JUV) e da uretra proximal (UP) em pacientes com incontinência urinária de esforço (IUE). MATERIAIS E MÉTODOS: Estudo prospectivo de corte transversal realizado na Unidade de Pesquisa em Incontinência Urinária da Universidade Federal de Pernambuco, de janeiro de 2002 a janeiro de 2005. Trinta e seis pacientes com queixas de IUE foram submetidas a ultra-sonografia perineal para avaliação da JUV e da UP com a bexiga praticamente vazia (< 50 ml), com aferição simultânea de pressão intra-abdominal. Para as avaliações, foi utilizado aparelho de ultra-som com transdutor vaginal de 7 MHz e seletor eletrônico de mensuração de imagem real, equipado com computador e câmera fotográfica de resolução instantânea. Para a medida da pressão intra-abdominal, foi utilizado aparelho de urodinâmica com cateter de 10 fr retal acoplado a um balão de sensor para medida da pressão intra-abdominal. RESULTADOS: As pacientes tinham idade entre 25 e 69 anos (média de 46,4 ± 10,2 anos). À manobra de Valsalva, a pressão intra-abdominal variou entre 7 cmH2O e 193 cmH2O (média de 99,3 ± 51,8 cmH2O; mediana de 99,5 cmH2O). Oito das 31 (25,8%) pacientes com hipermobilidade da JUV apresentaram pressão intra-abdominal inferior a 60 cmH2O. Não foi detectada relação estatisticamente significante entre a variação de pressão intra-abdominal e os parâmetros ultra-sonográficos em questão. CONCLUSÃO: Há um índice específico de pressão de deslocamento uretral para cada mulher com IUE. Porém, não há associação significativa entre o aumento de pressão intra-abdominal e aumento de mobilidade da JUV e UP em mulheres com quadro clínico de IUE. OBJECTIVE: To determine the influence of intraabdominal pressure in the ultrasonographic evaluation of the urethrovesical junction (UVJ) and proximal urethra (PU) in patients with stress urinary incontinence (SUI). MATERIALS AND METHODS: A prospective, cross-sectional study was conducted at the Urinary Incontinence Research Unit of "Universidade Federal de Pernambuco", Brazil, from January 2002 to January 2005. Perineal ultrasounds of the UVJ and PU were performed in thirty-six women complaining of SUI with the bladder virtually empty (< 50 ml); simultaneous measurement of the intraabdominal pressure was also performed. An ultrasound machine with a computer chip and a high-resolution photographic camera connected to a 7 MHz vaginal probe was used for the evaluation. In order to measure the intraabdominal pressure, an urodynamic equipment with a 10fr rectal catheter connected to a pressure sensitive balloon was used. RESULTS: The age of the patients ranged from 25 to 69 years (mean 46.4 ± 10.2 years). On Valsava maneuver, the intra-abdominal pressure ranged from 7 to 193 cmH2O (mean: 99.3 ± 51.8 cmH2O; median: 99.5 cmH2O). Eight out of 31 (25.8%) patients with UVJ hypermobility had an intraabdominal pressure lower than 60 cmH2O. There was no statistically significant association between intraabdominal pressure and the ultrasound parameters studied. CONCLUSION: There is a specific urethral pressure index for each woman with SUI. However, there is no significant association between increase in intraabdominal pressure and increase of UVJ and UP hypermobility in women with clinical SUI.

MÉTODOS: trabalho realizado na Unidade de Pesquisa em Incontinência Urinária da Universidade Federal de Pernambuco. Foram estudadas 22 mulheres com incontinência urinária de esforço foram submetidas à cirurgia do tipo TVT e avaliadas por ultra-sonografia antes e depois da cirurgia. RESULTADOS: os deslocamentos verticais médios da distância vertical da junção uretrovesical no pré e pós-operatório foram respectivamente de 16,7 mm e de 10,7 mm; e os deslocamentos médios da uretra proximal no pré e pós-operatório foram de 13,1 mm e de 6,7 mm (p=0,02). CONCLUSÕES: a cirurgia do tipo TVT, usada no tratamento de mulheres com incontinência urinária de esforço, reduz significativamente a mobilidade vertical da junção uretrovesical (p=0,005) e da uretra proximal (p=0,02). OBJECTIVES: to describe the urethrovesical junction and proximal urethra changes following Tension-free Vaginal Tape (TVT) procedure for stress urinary incontinence treatment (SUI). METHODS: this study was performed at the Urinary Incontinence Research Unit of the Universidade Federal de Pernambuco. Twenty two stress urinary incontinence female patients were submitted to TVT. They were evaluated through ultrasound before and following surgery. RESULTS: ultrasound results at rest, before and following TVT surgery, were: mean displacement of urethrovesical junction vertical length, before and after TVT procedure respectively 16,7mm and 10,7 mm; and mean displacement of proximal urethra length, before and following TVT surgery, respectively 13,1 mm and 6,7 mm. CONCLUSIONS: TVT surgery used for treating women with stress urinary incontinence significantly reduces the vertical mobility of the urethrovesical junction (p=0,005) and proximal urethra (p=0,02).

OBJETIVO: Investigar a influência do volume vesical na avaliação ultra-sonográfica da mobilidade da junção uretrovesical (JUV) e do comprimento da uretra proximal (UP) em mulheres com incontinência urinária de esforço (IUE). MATERIAIS E MÉTODOS: Mulheres com IUE submetidas à avaliação ultra-sonográfica da JUV e da UP com bexiga praticamente vazia (< 50 ml de urina) e com a bexiga cheia. RESULTADOS: As médias, em milímetros, dos parâmetros medidos com bexiga vazia e bexiga cheia foram, respectivamente: em repouso: distância vertical da JUV (DVJUV) de 15 e 13,5 (p = 0,3347), distância horizontal da JUV (DHJUV) de 14 e 15 (p = 0,3767), distância pubouretral (DPU) de 13 e 13 (p = 0,8065), UP de 15 e 14 (p = 0,8011); em esforço: DVJUV de 0 e 4 (p = 0,0281), DHJUV de 21 e 19,5 (p = 0,7501), DPU de 18,5 e 15 (p = 0,1592), UP de 0 e 4 (p = 0,0479); deslocamento: DVJUV de 16 e 15 (p = 0,0047), DHJUV de 6 e 5 (p = 0,3542), DPU de 7 e 5,5 (p = 0,1789), UP de 12 e 8 (p = 0,0496). CONCLUSÃO: Comparando bexiga quase vazia com bexiga cheia, há diferença significativa na avaliação ultra-sonográfica perineal da JUV e da UP apenas no esforço e sentido vertical, sendo que as pacientes com a bexiga quase vazia deslocam mais a JUV e a UP em relação à bexiga cheia.OBJECTIVE: To investigate the influence of bladder volume on perineal ultrasound assessments of the urethrovesical junction (UVJ) mobility and proximal urethral (PU) length in women with stress urinary incontinence (SUI). MATERIALS AND METHODS: Women with SUI were submitted to perineal ultrasound assessments of UVJ mobility and PU length with both full and practically empty (< 50 ml of urine) bladder. RESULTS: The means, in millimeters, of the measured parameters with a practically empty and full bladder were as follows: at rest: UVJ vertical distance (UVJVD) = 15 and 13.5 (p = 0.3347), UVJ horizontal distance (UVJHD) = 14 and 15 (p = 0.3767), pubourethral distance (PUD) = 13 and 13 (p = 0.8065), PU = 15 and 14 (p = 0.8011); on strain: UVJVD = 0 and 4 (p = 0.0281), UVJHD = 21 and 19.5 (p = 0.7501), PUD = 18.5 and 15 (p = 0.1592), PU = 0 and 4 (p = 0.0479); the resulting movements: UVJVD = 16 and 15 (p = 0.0047), UVJHD = 6 and 5 (p = 0.3542), PUD = 7 and 5.5 (p = 0.1789), PU = 12 and 8 (p = 0.0496). CONCLUSION: The comparison of UVJ parameters using perineal ultrasound with the bladder practically empty as well as full showed that vertical movement of the UVJ and PU length and their status on strain were significantly increased in patients with a practically empty bladder.

Pelvic ureteral injuries represent a serious surgical accident due to the potential damage they may cause to renal function. We report here the results of 19 years of experience with reconstruction of distal ureteral injuries by transperitoneal unstented reimplantation. This was a prospective cohort study undertaken at Barão de Lucena and University Hospitals, Recife (Brazil). Forty-seven patients with ureteral obstruction postgynecological surgery were routinely operated using the initial incision. The ureter was identified, dissected, and reimplanted through the peritoneal cavity. No stent was necessary. The average surgical time was 70 min (45-180 min). A psoas hitch or a Boari-Ockenblad bladder flap was required in six (12.8%) and four (8.5%) patients, respectively. Among 32 patients without fistula, 28 (87.5%) had complete and four (12.5%) had partial hydronephrosis regression without clinical repercussions. The cure rate was 100%. There were no complications. Routine primary unstented distal ureteral reimplantation using the transperitoneal approach is an effective and safe treatment strategy for injuries following benign gynecological surgery.

Objectives: We evaluated the efficacy of the bladder mucosa autograft technique in the treatment of vesicovaginal fistula. Study Design: During 15 years, 80 women with vesicovaginal fistula after gynecologic surgery for benign disease were treated by interposition of a bladder mucosa autograft in the fistulous tract within 1–3 months of its genesis. Results: The success rate of this surgical intervention was 96.3%. There was no late failure. Conclusions: Bladder mucosa autograft interposition seems to be an excellent therapy for closing vesicovaginal fistulas. It appears to be more physiologic and easier to perform when compared with other transabdominal techniques. Early intervention proved to be efficacious and to improve the woman's quality of life.

Objective: To compare sonographic pre- and post-op parameters related to the urethrovesical junction (UVJ) and proximal urethra (PU) in women with stress urinary incontinence (SUI) surgically cured or not with the Burch procedure, and to evaluate whether these can be used as prognostic markers. Methods: Thirty female patients were selected by convenience sampling and assigned into two groups: 15 patients considered as clinically cured (the case group) and 15 as not cured (the control group). The enrollees were submitted to pre- (30 days prior) and post-op (180 days after) transvulvar ultrasound assessments of the UVJ and PU. Results: On post-op assessments measured on strain, the vertical UVJ distance from the inferior pubic border and the PU length were significantly larger in cured patients (12.87 ± 5.80mm vs 5.13 ± 6.55mm in controls, P

To study the changes in the urethrovesical junction (UVJ) and in the proximal urethra (PU) caused by the Marshall-Marchetti-Krantz-Burch (MMK-B) combined surgery through perineal ultrasonography.An interventional, longitudinal and prospective study has been conducted. Thirty-two women with stress urinary incontinence were submitted to perineal ultrasonography before and 30 days after surgery to evaluate the pubo-urethral distance (PUD), the proximal urethra length, the UVJ horizontal distance (UVJHD) and the UVJ vertical distance (UVJVD), the patient being at rest, and in effort during the Valsava manoeuvre. Results have been expressed in mean and standard deviation. The Student's t-test has been used to compare pre and postoperative results whenever the variables fulfilled the normality test criterion; otherwise, the Wilcoxon's paired test has been used.As compared with the preoperative measures, the Marshall-Marchetti-Krantz-Burch surgery has reduced the PUD at rest (14 mm x 4.3 mm) and during effort (20.8 mm x 6.4 mm); has reduced the UVJHD at rest (14 mm x 4.3 mm) and during effort (20.8 mm x 6.4 mm); has increased the PU length at rest (16.7 mm x 19.7 mm) and during effort (1.6 mm x 15.4 mm); and has increased UVJVD during effort (-5.4 mm x 14.8 mm), but has not changed it at rest (16.2 mm x 18.7 mm, p = 0.085).The Marshall-Marchetti-Krantz-Burch surgery has significantly reduced the urethrovesical junction vertical and horizontal mobility without raising the urethrovesical junction.

Os parâmetros estudados foram: distância vertical e distância horizontal da junção uretrovesical, distância pubouretral e comprimento da uretra proximal. RESULTADOS: A distância vertical da junção uretrovesical não variou significativamente após a sling de fáscia lata (p > 0,10). A distância pubouretral e a uretra proximal tornaram-se menores (p < 0,003) e a distância horizontal da junção uretrovesical tornou-se menor só no repouso (p = 0,03) após a sling de fáscia lata. A tension-free vaginal tape diminuiu o deslocamento vertical da junção uretrovesical (p = 0,0005) e o comprimento da uretra proximal (p = 0,02). CONCLUSÃO: A ultra-sonografia transvulvar foi fundamental para documentar que as cirurgias de sling de fáscia lata e tension-free vaginal tape alongam a uretra proximal, sendo a sling de fáscia lata de forma mais eficaz. A sling de fáscia lata enfoca a diminuição da distância pubouretral e a tension-free vaginal tape, o deslocamento vertical da junção uretrovesical. OBJECTIVE: The aim of this study was to describe the role of transvulvar ultrasonography in the assessment of anatomical changes following fascia lata sling or tension-free vaginal tape procedures. MATERIALS AND METHODS: Forty women in the age range between 30 and 60 years had fascia lata sling (20 patients) or tension-free vaginal tape (20 patients) placement for treating stress urinary incontinence. Transvulvar ultrasonography was utilized, both pre- and post-operatively, as the main investigational tool in these cases for evaluating the urethrovesical junction vertical and horizontal distances, pubo-urethral distance and proximal urethra length. RESULTS: The urethrovesical junction vertical distance did not vary significantly after the fascia lata sling surgery (p > 0.10). Both the pubo-urethral distance and the proximal urethra length became shorter (p < 0.003), and the urethrovesical junction horizontal distance was reduced only at rest (p = 0.03). The tension-free vaginal tape procedure resulted in a reduction of the urethrovesical junction vertical distance (p = 0.0005) and of the proximal urethra length (p = 0.02). CONCLUSION: Transvulvar ultrasonography was of utmost importance in the demonstration that both the fascia lata sling and tension-free vaginal tape surgical procedures elongate the proximal urethra, even though the fascia lata sling technique does it more effectively. The fascia lata sling technique is more focused on shortening the pubo-urethral distance, and the tension-free vaginal tape, on the correction of the vertical displacement of the urethrovesical junction.

PURPOSE: To determine the influence of intra-abdominal pressure on the ultrasonographic evaluation of the urethrovesical junction (UVJ) and proximal urethra (PU) in women with stress urinary incontinence (SUI). METHODS: This is a prospective cross-sectional study undertaken at the Urinary Incontinence Research Unit (UIRU) of the Universidade Federal de Pernambuco (UFPE). Thirty-six women complaining of SUI underwent perineal ultrasound assessments of the UVJ and PU having the bladder barely empty (< 50 ml of urine) with simultaneous measurement of the intra-abdominal pressure (IAP). An ALOKA ultrasound machine with a 7 MHz vaginal probe was used for the assessments. In order to measure the IAP, an Uromaster MPX616 urodynamic equipment, connected to a 10Fr rectal catheter with a pressure sensitive baloon, was used. RESULTS: The participants' mean age was 46.4 ± 10.2 years. On maximum straining, the mean IAP was 99.3 ± 51.8 cmH(2)0, varying from 7 to 193 cmH(2)0, and the median was 99.5 cmH(2)0. Twenty-eight of 31 patients with UVJ hypermobility (90.3%) easily showed it with an IAP over 40 cmH(2)0. There was no significant association between the mean IAP measurements on maximum straining and the parameters studied. The IAP did induce a significant elongation of the proximal urethra length over 14 mm up to a cut-off over 80 cmH2O, most likely to increase urethral resistance and pressure profile, thus avoiding urine leakage. However, all 19 women with such a characteristic already presented so with an IAP > 40 cmH2O. CONCLUSION: There is no need to measure IAP routinely on perineal ultrasound assessments of the UVJ and PU in women with SUI having a barely empty bladder. OBJETIVO: Determinar a influência da pressão intra-abdominal na avaliação ultra-sonográfica da junção uretrovesical (JUV) e uretra proximal (UP) em mulheres com incontinência urinária de esforço (IUE). MÉTODOS: Este é um estudo de corte transversal prospectivo realizado na Unidade de Pesquisa em Incontinência Urinária (UPIU) da Universidade Federal de Pernambuco (UFPE). Trinta e seis mulheres queixando-se de IUE foram submetidas a aferições ultra-sonográficas perineais da JUV e UP com a bexiga praticamente vazia (< de 50 ml de urina) simultaneamente a medições da pressão intra-abdominal (PIA). Para tal foi utilizado um aparelho de ultra-som ALOKA com um transdutor vaginal de 7MHz. Com o intuito de medir a PIA, utilizamos o equipamento de urodinâmica Uromaster MPX616 conectado a um catéter retal de 10Fr com um balão sensível à pressão. RESULTADOS: A idade média das participantes foi de 46,4 ± 10,2 anos. No esforço máximo, a média de PIA foi de 99,3 ± 51,8 cmH(2)0, variando de 7 a 193 cmH(2)0, e a mediana foi de 99,5 cmH(2)0. Vinte e oito de 31 pacientes com hipermobilidade da JUV (90,3%) facilmente a revelaram com uma PIA acima 40 cmH(2)0. Não houve associação significativa entre a média de PIAs aferidas no esforço máximo e os parâmetros estudados. A PIA na realidade induziu a um alongamento significativo do comprimento da uretra proximal acima de 14 mm até um ponto de corte acima de 80 cmH2O, muito provavelmente para aumentar a resistência e características pressóricas uretrais, assim evitando a perda urinária. Entretanto, todas as 19 mulheres com tais características já as apresentavam com uma PIA > 40 cmH2O. CONCLUSÃO: Não há necessidade de se aferir rotineiramente a PIA nas avaliações ultra-sonográficas da JUV e UP em mulheres com IUE com a bexiga praticamente vazia.

OBJETIVO: Avaliar o volume testicular e a prevalência de varicocele em adolescentes e adultos jovens portadores de esquistossomose na forma hepatoesplênica associada a varizes sangrentas de esôfago. MÉTODOS: O estudo envolveu 22 adolescentes masculinos com esquistossomose na forma descrita, submetidos à esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico no grande omento quando crianças. O tempo médio de seguimento foi de 4 anos após a intervenção. O grupo de voluntários sadios foi de adolescentes de uma escola na mesma região onde os casos operados viviam. Eles foram selecionados de forma randomizada, considerando a faixa de idade, características epidemiológicas e não serem infestados por equistossomose. Todos os participantes possuíam história clínica completa e foram submetidos a exame físico e ultra-sonográfico. Foi dado atenção especial as características sexuais, ultra-sonografia testicular e dopplerfluxometria das veias espermáticas. RESULTADOS: Dos pacientes classificados como adultos pela idade cronológica, 53,8% tinham genitais com características infantis. A incidência de varicocele foi igual a 61,5% no grupo afetado e 40% no grupo controle, sem diferença estatística entre os grupos (x 2 =1,77; g.1.=1; p=0,18 3 p Fisher=0,16), acometendo predominantemente o testículo esquerdo, em ambos os grupos. CONCLUSÃO: Pacientes com doença esquistossomótica cirúrgica tinham significante déficit no desenvolvimento puberal e genital, no volume testicular, especialmente do lado esquerdo, e alta prevalência de varicocele (61.5%) sem uma associação direta com atrofia testicular. PURPOSE: This case-control study was aimed at evaluating testicular volume, puberal and genital development, and the prevalence of varicocele in adolescents and young adults with shistosomiasis in the hepatosplenic form associated with bleeding esophageal varices. METHODS: The study involved 22 young males with schistosomiasis as described, submitted to splenectomy, left gastric vein ligature and auto-implant of splenic tissue in the greater omentum during childhood. The mean follow-up period was 4 years after surgery. The control group included healthy volunteers from a school in the same region where the cases lived. They were randomly selected, matched by age and epidemiological characteristics, and had schistosomiasis ruled out. All participants had complete history taken and were submitted to a thorough clinical and ultrasonographic examinations. Special attention was given to sexual characteristics, testicular ultrasonography and dopplerfluxometry of spermatic veins. RESULTS AND CONCLUSIONS: Patients with schistosomiasis had significant deficits in puberal and genital development, testicular volume, specially the left one, and a high prevalence of varicocele (61.5%) without a straight association with testicular atrophy.

Este trabalho tem por objetivo mostrar as alterações anatômicas da junção uretrovesical (JUV) e da uretra proximal (UP) decorrentes da cirurgia do tipo Kelly-Kennedy. Foram determinadas por ultra-sonografia transvulvar da JUV e da UP as medidas da distância vertical e horizontal da JUV (DVJUV e DHJUV), distância pubouretral (DPU) e da UP, no período pré-operatório e 30 dias após a cirurgia para tratamento de pacientes com Incontinência Urinária de Esforço (IUE). Os autores concluíram que a cirurgia empregada promoveu melhora significativa dos graus de IUE, cura da cistocele e da retocele em todas as pacientes. Em relação ao bordo inferior da sínfise púbica, houve uma modificação da posição vertical da JUV, no sentido cranial, na situação de repouso, reduzindo significativamente sua mobilidade no esforço, ao passo que, na horizontal, observou-se uma redução da DHJUV, tanto no repouso quanto no esforço. Ainda ficou caracterizada uma redução da DPU na situação de repouso, ocasionando menor mobilidade ao esforço, em valores estatisticamente significantes, assim como um aumento no comprimento da UP, no repouso e no esforço. The aim of this study was to show the anatomical alterations of the urethrovesical junction (UVJ) and proximal urethra (PU) carried out after Kelly-Kennedy type surgery. It was determined, by transvulvar ultrasonographic, of the UVJ and the PU the measures of the vertical and horizontal distances of the UVJ (DVUVJ and DHUVJ), pubourethral distance (DPU) and of the PU, in the pre-operative period and 30 days after the surgery for handling of patients with stress incontinence. It was concluded that the employed surgery promoted significant improvement of the degrees of stress incontinence, cure of cystocele and of retocele in all the patients. In relation to the lower board of the pubic simphisis, surgey moved the vertical position of UVJ, in the cranial direction, in the rest position, significantly, reducing its mobility in the effort. It also reduced DHUVJ, so much in rest as in effort. Furthermore, it promoted a reduction of PUD in the rest position, creating smaller mobility in effort, in statistically significant figures, as well as an increase in the length of PU, both in rest and the effort.

Objective: To describe the relevance of transvulvar ultrasound in the assessment of anatomical differences induced by the lata fascia sling (LFS) and tension-free vaginal tape (TVT) procedures. Materials and Methods: Forty women with stress urinary incontinence (SUI), aged 30 to 60 years, have been treated with either LFS (20 patients) or TVT (20 patients). The transvulvar ultrasound of the urethrovesical junction (UVJ) and proximal urethra (PU) has been used as the main investigational tool both pre- and post-operatively. The studied parameters were the vertical (VUVJD) and horizontal (HUVJD) UVJ distances, the pubourethral distance (PUD) and the PU length. Results: The VUVJD did not vary significantly after the LFS surgery (P=0.10). The PUD became shorter (P=0.001) and the HUVJD became shorter only at rest (P=0.03) after the correction by LFS. The TVT procedure has led to shortening of the VUVJ displacement (P=0.0005) and of the PU length (P=0.02). Conclusions: The transvulvar ultrasound was of utmost importance in the demonstration that both the LFS and TVT surgical procedures elongate the PU, even though the LFS technique does it more efficiently. The LFS technique focus more on shortening the PUD and the TVT procedure focus more on the correction of the vertical UVJ displacement.
