Carbon dioxide pneumothorax following retroperitoneal laparoscopic partial nephrectomy: a case report and literature review.

Retroperitoneal laparoscopic surgeries are likely to bring about severe capno-thorax, which could be absorbed rapidly. Chest X-ray could be used to assist diagnosis but point-of-care transthoracic ultrasound is recommended. Even severe capno-thorax could be treated conservatively. This case highlights the awareness and therapeutic choice of noninvasive management for capno-thorax.
