Urinary Bladder and Ureters MCQs

Explanation: The Weigert-Meyer law describes the anatomical relationship of the upper and lower renal moieties in duplicated collecting systems and their corresponding inferior drainage into the bladder. Weigert Meyer's rule states that The upper and lower renal moieties each have separate ureters, each with its own orifice in the bladder. The upper renal moiety ureter typically inserts ectopically, medially and inferior to the lower renal moiety ureter, often leading to a The lower renal moiety ureter inserts orthotopically , laterally, and superiorly to the upper moiety's ureter, which has a risk of vesicoureteral reflux.

Explanation: Early post-cholecystectomy subhepatic collections are most often due to a bile leak, commonly from the cystic duct stump or an accessory bile duct. Explanation of other options: Infection (Option A): Takes 5-7 days to develop; not an early cause of subhepatic collection. Surgical site pain (Option B): Does not explain fever, tachycardia, or localized fluid collection. Retained gallstones (Option D): Can cause colic or cholangitis, but not an early subhepatic collection.

Explanation: The normal urine output is around 1500 ml/day for a healthy adult, which roughly translates to 0.5-1.5 ml/kg/hour . (1x70(kg)x24(hours) ~ 1700 ml). Minimum urine output to excrete end products of protein metabolism: 500ml/day Ideal urine output in a normal 70kg adult: 1500 ml

Answer- A. Ileum Ileal segment is the best for urinary diversion after cystectomy. Still better method is "Continent cutaneous diversion" method. But the best method is "Orthotopic neobladders".
