Gas-forming renal abscesses in critically ill patients: ultrasound-guided drainage

PURPOSE

This study aimed to describe and evaluate a real-time ultrasound-guided (US-guided) drainage technique for effective and safe drainage of gas-forming renal abscesses (GRA) in an intensive care unit(ICU).

MATERIALS AND METHODS

This retrospective study included four patients with GRA who were admitted to the ICU of a tertiary care center between September 2021 and September 2023. The patients were all comorbid with severe systemic infections and required drainage of abscesses for infection control. This study describes in detail the process of rapid and precise US-guided drainage of GRA by an ultrasound interventionist through certain maneuvers and techniques.

RESULTS

Six US-guided drainage procedures were completed in four patients, and seven catheters were placed accurately in the abscesses with a 100% success rate. No intraoperative or postoperative complications such as bleeding and peripheral organ damage were observed, and the median time with catheters was 13 days (8-46 days).

CONCLUSION

The technique of real-time US-guided drainage of GRA can be performed safely in the ICU without the need to leave the ICU, greatly reducing risk.

Autosomal Dominant Polycystic Kidney Disease with Emphysematous Polycystic Renal Infection That Required Surgical Treatment

We encountered a patient with autosomal dominant polycystic kidney disease (ADPKD) complicated with emphysematous polycystic renal infection (EPRI). A 44-year-old woman visited our hospital for a fever, appetite loss, and gross hematuria. Because the patient was suffering from end-stage renal disease (ESRD), she was immediately hospitalized for hemodialysis. Multiple emphysematous infected cysts were noted in the right kidney, and antibiotic therapy and three rounds of cystic drainage were performed. However, the patient did not respond to treatment. Therefore, laparoscopic right nephrectomy was performed. ADPKD with comorbid EPRI is unresponsive to conservative treatment, and we believe that nephrectomy should be considered.

Emphysematous polycystic renal infection

Autosomal dominant polycystic kidney disease (ADPKD) is one of the commonest hereditary disorders. Urinary tract infection is a common complication of this disease. However emphysematous infections in ADPKD have seldom been reported. We report a case of emphysematous polycystic renal infection with Gram negative (Escherichia coli) septicemia in a nondiabetic patient with ADPKD who succumbed to his illness despite aggressive management including early nephrectomy.
