腎臟發育不全為一側或雙側腎臟未發育的先天畸形。單側者對側腎臟代償性肥大，多數可正常生活。雙側者與生命不相容。偶見於犬貓的偶然發現。
犬貓均有報告。單側為主。比格犬可能有較高發生率。

建議：0.9% NaCl 或 LRS，矯正脫水後以 2× 維持量支持 post-obstructive diuresis

建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
單側腎臟發育不全預後良好，多數可正常生活。需保護唯一腎臟。對側腎臟的長期健康決定預後。
Diagnostic Approach for Renal Agenesis
Assess for dysuria, hematuria, pollakiuria, stranguria; palpate bladder and kidneys
Complete urinalysis via cystocentesis; urine culture and sensitivity for bacterial infection
Abdominal radiographs and ultrasound to evaluate urinary tract for calculi, masses, or structural changes
