Hormonal and hemodynamic changes during percutaneous nephrolithotomy.
The aim of this study was to investigate the hormonal and hemodynamic changes during percutaneous nephrolithotomy (PCNL) procedure. Twenty-one patients between 15-65 years of age were included in the study. Invasive blood pressure and heart rate were monitored during PCNL. Serum sodium, potassium, BUN and creatinine levels were measured before and after the operation. Sodium and potassium levels were also measured during the operation. Arterial blood gases, renin, aldosterone and adrenocorticotrophic hormone (ACTH) levels were measured before and during irrigation. The mean systolic and diastolic blood pressure levels were significantly higher (p < 0.05) during PCNL compared to post-procedure levels while heart rate remained constant. Serum sodium, potassium bicarbonate and base-excess levels were decreased during the operation compared to the baseline levels (p < 0.001). BUN and creatinine levels remained unchanged during the study (p > 0.05). In conclusion, a tendency to hyponatremia and metabolic acidosis developed in addition to significant increases in renin, aldosterone and ACTH levels during PCNL procedures. These changes may be due to the invasive nature of the intervention to the kidney and the continuous irrigation of this vital organ. This should be taken into consideration during PCNL. More detailed studies with larger groups are needed for more precise comments on this topic.
