Perfil epidemiológico e métodos diagnósticos de pacientes com nefrolitíase, atendidos no Serviço de urologia da Fundação Hospital Adriano Jorge nos anos de 2010 a 2012, na cidade de Manaus- Amazonas

Abstract

Nephrolithiasis is considered in some studies as a public health problem. It is estimated that 5 to 15% of the world population will present some renal calculus throughout life, being among the group most susceptible individuals of the male (3: 1), Caucasian and young, especially between 20 and 40 years. It is important to emphasize that lithiasis has high rates of recurrence. The tomography helical CT scan has played an important role in the diagnosis and treatment of renal lithiasis, and in the last years it has been considered by some authors as a "watershed," a role previously attributed to excretory urography (UE). Sixty-six patients, mostly males, were analyzed, most of them between the ages of 20 and 40 years. In all, 82% had nephrotic colic, 12% had a urinary tract infection and 6% incidental diagnosis. 42% performed abdominal x-ray at baseline, 86% performed at least one ultrasonography of the kidneys and urinary tract, 33% were submitted to computed tomography, 97% collected urine sample for EAS, 48% collected 24-hour urine, 6% underwent excretory urography, and in 62 patients (94%) were asked for serum biochemistry. The most employed was dietary guidance (97%). With regard to surgical treatment, 25 surgeries, with 6 complications, all self-limiting. Finally, regarding the outcome of these patients: 34 (52%) had resolution of the disease, with no recurrences in the period of study; 17 (26%) had recurrence of the disease, with 16 patients exclusive clinical treatment and only one relapse after surgical treatment (LECO); and treatment failure in 15 patients (23%), of which 12 were referred for a first or new surgery. This study reaffirms the Most of the indicators of other national and global studies for hospitals involved.Keywords: Nephrolithiasis; Epidemiology; Manaus; Treatment
