Transurethral Resection of Prostate (Turp): Surgery Without Using a 3-Way Catheter
Bibliographic record
Abstract
Transurethral resection of the prostate (TURP) continues to be an effective intervention for certain indications; and this procedure is still one of the most commonly performed in urology. The use of a 3-way catheter with continuous bladder irrigation (CBI) post-TURP is widely practiced in a bid to prevent clot retention. We report our unique experience with the use of 2-way urethral catheters post-TURP surgery. Methodology Data was prospectively collected for 143 consecutive patients who underwent a bipolar TURP between July 2015 and October 2017. The following outcomes where measured and compared against the literature: resection time, resected weight, haemoglobin level, hospital stay, catheterization days, transfusion rate and complications. Results Two-way 18-French catheters were used in 132/143 (91.7%) patients. The remaining 11/143 (8.3%) patients had a 3-way 22-French catheter and CBI immediately post-TURP. There were no incidences of clot retention requiring a return to theatre. There were 2/132 (1.5%) patients requiring transfusion who received 2-way catheterization. The average resection time was 44.8 (10-100) minutes, with a mean resected weight of 22.8 (2.0-70.0) grams. Post-operatively, we found minimal drop in haemoglobin levels, with a fall of 0.7 g/dL on average, with a range of 0.1-3.4 g/dL. Mean length of stay following TURP was 1.45 days (1-18), and 101/132 (76.5%) of patients had a successful trial without catheter on the first post-operative day. Conclusion Our outcomes compare favorably with the published data. This study suggests it may be possible to reduce the cost and resources associated with the use of 3-way catheters and CBI post-TURP surgery by using a 2-way catheter instead. Despite this, appropriate patient selection for this novel technique needs to be adopted. Our results would suggest that patients with smaller prostates or limited resections might be suitable for a 2-way urethral catheter post-TURP.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
