RESUMO Objetivou-se neste estudo obter os coeficientes de cultivo para a cultura da cebola e avaliar a influência de diferentes lâminas de irrigação (0, 22, 45, 75 e 100% da evapotranspiração da cultura) na produtividade comercial e na qualidade de bulbos de cebola, cultivada com e sem cobertura vegetal morta de capim-elefante no solo. O experimento foi realizado em Seropédica, RJ, Brasil, entre maio e setembro de 2012, em um Argissolo Vermelho-Amarelo. O delineamento experimental adotado foi em blocos casualizados em parcelas subdivididas, com10 tratamentos e sete repetições. O manejo da irrigação foi realizado por meio do balanço de água no solo utilizando a técnica da Reflectometria no Domínio do Tempo, a partir de sondas instaladas horizontalmente a 7,5 e 22,5 cm de profundidade. A utilização da cobertura morta permitiu a aplicação de menores lâminas de irrigação, proporcionando coeficientes de cultivo inferiores (18% no estágio II e 3% no estágio III) ao cultivo sem cobertura do solo. A lâmina de irrigação associada ao uso da cobertura vegetal morta no solo influenciou as variáveis de produção avaliadas, demonstrando ser uma alternativa para elevar a produtividade comercial e a qualidade de bulbos de cebola com menor lâmina de irrigação.

ABSTRACT The objectives of this study were to obtain the onion crop coefficients and evaluate the influence of different irrigation depths (0, 22, 45, 75 and 100% of crop evapotranspiration) on marketable yield and quality of onion bulbs cultivated with and without mulch of elephant grass. The experiment was carried out in Seropédica, RJ, Brazil, from May to September 2012, in a Red Yellow Argisol. The experimental design was in randomized blocks in split plots, with 10 treatments and seven replicates. Irrigation management was performed through soil water balance using the Time Domain Reflectometry technique, with probes installed horizontally at 7.5 and 22.5 cm depths. The use of mulch allowed the application of smaller irrigation depths, leading to lower crop coefficient (18% in stage II and 3% in stage III) in comparison to the crop without mulch. Irrigation depths associated with the use of mulch influenced the evaluated production variables, proving to be an alternative to increase marketable yield and quality of onion bulbs, with lower irrigation depth.

OBJECTIVE: The aim of this study was to present the results of pubovaginal sling with a low-cost polypropylene mesh in the treatment of stress urinary incontinence MATERIALS AND METHODS: 118 women diagnosed with stress urinary incontinence (SUI) due to urethral hypermobility or intrinsic sphincteric deficiency, treated with pubovaginal sling (PVS) with a low-cost polypropylene mesh confectioned by the surgeon, were analyzed. All patients had a basic evaluation that included a medical history, physical examination, stress tests and urodynamic investigation RESULTS: The average follow up was of 42 months. Urethral hypermobility was observed in 67% of the cases. The process was carried out on an outpatient basis on 67 patients. Intra-operative complications included 4 vesical injuries, treated with catheterization for 3 days. There were 13 early complications, of which 8 were urinary retentions treated with vesical drainage for 1 to 3 weeks and 3 vaginal extrusions of the mesh treated with covering of the sections with mucous membrane. There was a need for 6 urethrolysis in patients who presented irritative and postoperative obstructive symptoms; 81.3% of the patients were considered cured, while 9.3% had significant improvement. Three initially unsuccessful cases required sling reconfiguration. All cases were eventually cured CONCLUSION: The construction of a pubovaginal sling using a low-cost polypropylene mesh is a safe and effective technique for the relief of SUI. It should be considered an alternative, especially for patients in public health systems with low financial resources.
