Training on bench models improves dexterity in ureteroscopy.

INTRODUCTION: There is a need for alternative training in endourology. Computerised simulators have been introduced but have, so far, not been compared to real surgery. Bench models have proved to be comparable to real surgery when performing standard procedures in the upper urinary tract. OBJECTIVE: To validate training on bench models as a tool to improve dexterity in semi-rigid ureteroscopy. METHODS: Urology residents were tested when performing semi-rigid ureteroscopy on a bench model (Mediskills), before and after training. All standard equipment and instruments, including fluoroscopy, were available. For the test procedure we used a task-specific checklist and a global score (maximum score 10 + 9 = 19). After base line assessment, the participants practised under supervision. After training they were reassessed, using the same procedure as previously. RESULTS: The performance was significantly better after the training. Results before/after were: 5.1/9.2, 2.6/7.8 and 7.7/17.2 for task-specific checklist, global score and total score respectively. All residents felt more familiar with the instruments and the procedure after the training. CONCLUSION: Training on bench models for ureteroscopy enhanced the manual dexterity as well as familiarity with the method and is recommendable before operating on patients.

Validation of a bench model for endoscopic surgery in the upper urinary tract.

OBJECTIVE: Open surgery is increasingly replaced by endoscopic techniques. In urology, endoscopic procedures of the upper urinary tract are still evolving. The surgical techniques imply high accuracy and are difficult to teach since they are "one man" procedures. Training on bench models has essentially given promising results in general surgery but has never been validated for advanced endourology. In this study, ureteroscopy on a bench model was compared to the same procedure on patients. MATERIAL AND METHOD: Fourteen urologists, trainees and consultants, were scored using a task-specific check list and a global score when performing rigid ureteroscopy on patients and on a bench model from Mediskills. The participants had not seen the check lists before the performance and the scoring was carried out by the same person in all cases. RESULTS: The urologists performed equally on patients and the model and they all considered the procedure on the model similar to real surgery. There was no statistical difference in the score between consultants and trainees but those urologists (five consultants and three senior registrars) who were sub-specialised in endourology scored significantly higher than the others on both patients and the model. CONCLUSIONS: Bench models are comparable to real surgery for, at least basic, endoscopic procedures in the upper urinary tract. The models are also useful for making the trainees familiar with the operating instruments.

Imaging for microscopic haematuria.

For evaluation of the upper urinary tract, intravenous urography has for many years been the method of choice. In recent years, different imaging protocols have been suggested. In this article different strategies for the evaluation of microscopic haematuria, with a focus on the advantages and disadvantages of different imaging modalities, will be discussed.
