Calyceal diverticula were uncommon occurrences that might be difficult to control. Researchers reviewed and summarized literature with an emphasis on recent improvements in the treatment of calyceal diverticula, and analyzed the benefits and drawbacks of each surgical method. Calyceal diverticula required a high level of suspicion and contrast-enhanced imaging to be identified. The ease of access to contrast-enhanced CT imaging has surpassed traditional methods of visualizing the renal collecting system, such as the classic intravenous urography. Traditional surgical approaches for treating calyceal diverticula were not being phased out in favor of newer techniques; rather, existing technology was being upgraded and advanced. The ideal therapeutic technique for the management of symptomatic calyceal diverticula was still up for debate, with the option largely dependent on the location and anatomy of the diverticulum itself.
The most important advancement in the treatment of calyceal diverticula and stones, in general, appeared to be the growing miniaturization of percutaneous nephrolithotomy (PCNL) equipment, which allowed successful treatment while reducing the dangers associated with traditional PCNL. Although robotics was becoming more accessible, it was unlikely to replace flexible ureteroscopic (fURS) or percutaneous techniques in the treatment of the problem. Striking a balance between therapy efficacy and invasiveness is key to the future of surgical treatments for this illness.
