Taiwan: A totally tubeless single tract mini-percutaneous nephrolithotomy (PCNL) for treating large bursena>2 cm and/or complex renal stones ensures feasible stone-free rate (SFR), short hospital stay, and low morbidity shows a case series of 62 patients. Further, the totally tubeless manner was not tied to an increased risk of postoperative morbidity and decreased use of postoperative analgesics worked in favor of the patients. The study was published in the journal BMC Urology on 16 April 2022.

The use of totally tubeless mini-percutaneous nephrolithotomy for treating large renal stones is backed by limited literature. In the study, Pao-Hwa Chen, Department of General Surgery, Division of Urology, Changhua Christian Hospital, Changhua City, Taiwan, and colleagues present findings of treating patients with large and/or complex renal stones using single renal access totally tubeless mini-PCNL.

For this purpose, the researchers enrolled 62 consecutive cases, all with calculi > 2 cm, in which a single tract totally tubeless mini-PCNL was used to treat complex renal stones from March 2018 to May 2021. All procedure of puncture and dilation were guided by a fluoroscope. The Guy's Scoring System (GSS) was used to assess the complexity of stones. The surgical duration, perioperative morbidity, analgesia requirement, length of hospital stay, and stone-free rate were assessed.

The study led to the following findings:

· The mean preoperative stone burden was 36.69 ± 19.76 mm (above 2 cm in all cases), mean surgical duration was 61.93 ± 40.84 min (range 15–180 min), and mean hematocrit reduction was 4.67 ± 2.83%. Postoperative Nalbuphine was used in 6 patients.

· The mean length of stay was 2.46 ± 1.19 days, and the postoperative stone-free rate was 83.9% (52/62), and 87.1% (54/62) after auxiliary ESWL.

· The overall complication rate was 14.5%, the majority of complications being postoperative transient fever.
