Abstract
We report the case of syndrome of inappropriate anti-diuretic hormone secretion (SIADH) following transurethral resection of bladder tumour (TURBT) surgery. An 88-year-old man was admitted to our hospital for TURBT. The clinical course after surgery was good ; however, he began to feel nausea on post-operative day 8. His serum sodium level was 105 mEq/ L, and other clinical findings satisfied all criteria for SIADH. Pathological findings of the TURBT specimen showed no evidence of an endocrine-producing tumour. We assume that the combination of advanced age, TUR surgery stress and vomiting ultimately led to SIADH in this patient. This case is a very rare phenomenon as it involves both SIADH with bladder cancer and SIADH following TURBT. SIADH should be taken into consideration when elderly patients are undergoing any type of surgery.
