DS Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)

Study Overview
=================
Brief Summary
-----------------
Prospective, monocentric, single arm, observational PMCF - Study on the Performance and Safety of Double-Shank Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)

Detailed Description
-----------------
The objective of this observational study is to collect systematically and proactively data regarding the Aesculap® DS Titanium Ligation Clip under daily clinical practice when used in urology in different indications. The hypothesis of this study is that this event, slippage / movement of the clip, is extremely rare through the design if used in accordance with the Instructions for Use (IfU). The observed rate through the total number of clips might be a valuable parameter and could influence future research. Furthermore, this study is one of the PMCF measures which enable the manufacturer to monitor the safety and performance of the Aesculap® DS Titanium Ligation Clips. The products bear the CE-marking and are routinely used within this institution for the above-mentioned procedures.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of slippage / movement of the clip in relationship to the total number of used clips. | Slippage / movement of the Aesculap® DS Titanium Ligation Clip is an observable slippage, movement, or rotation after the clip was successfully applied and the application forceps was removed. The number of observed slippage / movement of the clip will be documented on the CRF, the clip size, step of the procedure and further measures were necessary, i.e. removal of the clip or application of another clip, will be documented. In the end the rate will be brought in relationship to the overall number of applied clips. Thus, the number of applied clips is documented, for each clip size. | Intraoperatively | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of Adverse events (intra- and postoperative) | Postoperative bleedings Infections Urine extravasation in partial nephrectomy Prolonged urinary catheter drainage in radical prostatectomies Ileus Venous thrombo-embolic events Sepsis Other | up to discharge from hospital (approximately 10 days post surgery) |
