The objectives of urinary diversion have progressed from simply diverting urine through a conduit to orthotopic reconstruction. This approach provides a safe and continent means to store and eliminate urine, aiming to improve the patient's quality of life. A neobladder enables patients to maintain a normal lifestyle and better self-image after bladder removal by creating a natural extension of continent, cutaneous urinary diversion that is directly connected to the native urethra. Importantly, this does not compromise oncological outcomes. Long-term functional results of orthotopic ileal W-neobladder with serous lined extramural ureteric implantation have been demonstrated to be effective and durable in various studies. Over the past decades, significant advancements have been made in understanding bladder carcinoma and neobladder construction. Our study analyzes the short- and long-term functional outcomes of neobladder reconstruction in patients who underwent radical cystectomy at our center. We also compare our functional results of orthotopic neobladder reconstruction with those of a previous pilot study.
