Key result
Hemodialysis and bilateral nephrostomy tubes slowly resolve extreme ~10 mmol/L hyperkalemia in malignant ureteric obstruction.
Why the study?
Extreme hyperkalaemia secondary to malignant ureteric obstruction is a rare and life-threatening condition with limited clinical reports on management and outcomes.
Case Report (n=1)
Survival and recovery are possible even with extreme hyperkalaemia (K+ 10.3 mmol/L) when treated promptly with haemodialysis and relief of obstruction.

Reversible renal failure may permit recovery from extreme electrolyte derangements; this case leaves open the biochemical thresholds incompatible with life.
We report a case of a 42 year old patient who collapsed at an airport departure lounge. The patient was investigated and found to have advanced renal failure with serum potassium (K+) of 10.3 mmol/L, creatinine of 3581 pmol/L and urea of 59.9 mmol/L secondary to obstructive uropathy due to advanced bladder cancer. Although these biochemical changes were thought to be incompatible with life, he made a slow recovery following haemodialysis and insertion of bilateral percutaneous nephrostomy tubes.

Ali et al. (2007) conducted a case report in Extreme hyperkalaemia secondary to malignant ureteric obstruction (n=1). Haemodialysis and bilateral percutaneous nephrostomy tubes was evaluated on Recovery. Haemodialysis and bilateral percutaneous nephrostomy tubes led to a slow recovery in a 42-year-old man with extreme hyperkalaemia (10.3 mmol/L) secondary to malignant ureteric obstruction.
