A Comparison of Early Results and Patient Satisfaction Rate between Modified Radical Cystectomy with Mainz II Urinary Diversion and Standard Radical Cystectomy with Continent Ileocecal Urinary Diversion
Bibliographic record
Abstract
Background: This study compared the early success, complication and patient satisfaction rates of modified extraperitoneal radical cystectomy (Mainz II urinary diversion) with standard intraperitoneal radical cystectomy (continent ileocecal urinary diversion) in a group of patients with muscle invasive urothelial carcinoma of the urinary bladder. Methods: From September 2009 until November 2013, this randomized study enrolled 60 patients with muscle invasive transitional cell carcinoma of the urinary bladder who underwent radical cystectomy and urinary diversion. The patients were randomly allocated to two groups via block randomization. Group A included 30 patients (28 men and 2 women) who underwent modified small incision extraperitoneal radical cystectomy with a Mainz II urinary diversion. Group B included 30 patients (27 men and 3 women) who had classic intraperitoneal radical cystectomy and ileocecal continent diversion. The data were extracted and analyzed. The patients were followed for one year after surgery. Results: Group A patients had a mean age of 61.47±8.63 years. Group B patients had a mean age of 60.77±6.82 years. There were no statistically significant differences in blood loss, electrolyte and acid-base abnormalities, and early post- operative complication rates between the two groups. However, surgical and hospitalization times were significantly shorter in group A (P<0.001). In addition, patients were mobilized earlier and had shorter nothing by moth time. Patient satisfaction rate was significantly more in group A. Conclusion: Small incision extraperitoneal radical cystectomy and Mainz II urinary diversion is a safe, less complicated, effective and more rapid technique with excellent short term outcome. It seems this technique is a reliable alternative for continent urinary diversion in selected bladder cancer patients, mainly in those with urethral involvement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
