Table 3 Summary of postoperative complications using Clavien-Dindo classification.
| Complication | Group 1 NFTS-UAS (n) | Group 2 PCNL (n) | Clavien-Dindo Grade | Description |
|---|---|---|---|---|
| Fever (>37.5°C) | 10 | 91 | I–II | Mild to moderate fever, typically managed with antipyretics or antibiotics |
| Subcapsular hematoma | 0 | 6 | II–III | Hematoma beneath the renal capsule, which may require transfusion or intervention |
| Steinstrasse | 10 | 4 | II–III | Postoperative ureteral obstruction due to stone fragments, which may require intervention |
| Ureteral stricture | 11 | 29 | III–IV | Ureteral narrowing, often requiring endoscopic or surgical intervention |
| Pyonephrosis | 3 | 7 | III–IV | Infection of the renal pelvis, may require drainage or antibiotics |
| Septic shock | 0 | 1 | V | Life-threatening infection-induced shock requiring intensive care |
| Renal artery embolism (DSA) | 0 | 1 | IV–V | Embolization of renal artery, potentially leading to significant morbidity |
| : Any deviation from the normal postoperative course without the need for pharmacological treatment or invasive procedures. : Requiring pharmacological treatment with drugs other than those allowed for Grade I complications. : Requiring surgical, endoscopic, or radiological intervention. : Life-threatening complications requiring intensive care unit (ICU) management. : Resulting in the death of the patient. | ||||
