RESUMO
Abstract Ascites and oliguria with an increasing serum creatinine level are often observed in patients with acute renal failure. However, these symptoms are also noted in individuals with intraperitoneal urinary leakage and can be mistaken for acute renal failure. This rise in creatinine in such patients is called pseudo renal failure and it happens by a process of reverse peritoneal dialysis. In literature, the most commonly described condition that leads to this clinical picture is following a spontaneous or missed bladder perforation. We, herein, report a case of carcinoma of the bladder that presented with features resembling acute renal failure, which later turned out to be pseudo renal failure due to intraperitoneal urinary extravasation from a forniceal rupture. The patient was managed with emergency with a percutaneous drain followed by a percutaneous nephrostomy, which led to normalization of creatinine. Cystoscopy revealed the bladder growth in an intact small capacity bladder and biopsy confirmed it as a muscle invasive squamous cell carcinoma. Due to advanced nature of his malignancy, he underwent a palliative ileal conduit diversion but he later developed chest metastasis and ultimately succumbed to the disease. Intraperitoneal urinary leakage due to forniceal rupture presenting as pseudo renal failure is a rare presentation of carcinoma bladder. Sudden onset abdominal discomfort, increasing ascites, hematuria, and oliguria with elevated renal parameters needs consideration and exclusion of this entity. The diagnostic dilemma associated with this rare presentation along with the management and prognosis in such patients of carcinoma bladder are discussed.
Resumo Ascite e oligúria com um nível crescente de creatinina sérica são frequentemente observadas em pacientes com insuficiência renal aguda. Entretanto, esses sintomas também são notados em indivíduos com extravasamento urinário intraperitoneal e podem ser diagnosticados como lesão renal aguda erroneamente. Este aumento de creatinina em tais pacientes é chamado de pseudo insuficiência renal e ocorre por um processo de diálise peritoneal reversa. Na literatura, a condição mais comumente descrita que leva a este quadro clínico se dá após uma perfuração vesical espontânea ou perdida. Relatamos aqui um caso de carcinoma de bexiga que apresentou características semelhantes à insuficiência renal aguda, e mais tarde se revelou uma pseudo insuficiência renal devido a extravasamento urinário intraperitoneal de uma ruptura de fórnice renal. O paciente foi tratado com emergência com um dreno percutâneo seguido por uma nefrostomia percutânea, que levou à normalização da creatinina. A cistoscopia revelou o crescimento da bexiga em uma bexiga intacta, de pequena capacidade e que a biópsia confirmou como um carcinoma escamoso invasivo muscular. Devido à natureza avançada de sua malignidade, ele foi submetido a um desvio de conduto ileal paliativo, mas posteriormente desenvolveu metástase torácica e acabou sucumbindo à doença. O vazamento urinário intraperitoneal devido à ruptura do fórnice renal que se apresenta como pseudo insuficiência renal é uma apresentação rara do carcinoma vesical. Desconforto abdominal de início súbito, ascite crescente, hematúria e oligúria com elevados parâmetros renais precisam de consideração e exclusão desta entidade. O dilema diagnóstico associado a esta rara apresentação, juntamente com o controle e prognóstico em tais pacientes de carcinoma vesicular, são discutidos.
RESUMO
Study was conducted to assess the sensitivity and simplicity of various pain rating scales in patients of osteoarthritis with chronic pain so that most appropriate scale can be identified. Scales included were Wong- Baker Faces Pain Rating Scale (WBS), Numerical Rating Scale (NRS), Faces Pain Scale- Revised (FPS-R), Visual Analogue Scale (VAS) and Verbal Rating Scale (VRS). Patients were asked to indicate their pain on these scales and comment about the simplicity of scales. Median mark for WBS, NRS, FPS-R, VAS and VRS was 10, 10, 10, 9.1 and 10 respectively. P value between WBS, NRS, FPS-R, VAS and VRS was insignificant. Most simple, easy to answer scale (83%) was WBS followed by FPS-R (17%). We conclude that all the scales are sensitive for assessment of the chronic osteoarthritis pain and are not different from each others. The most simple and preferred pain rating scale is WBS for the regional population.
