However, the appropriate frequency of urinary drainage bag change needs additional study because the sample size in this study does not rule out a false-negative result.
We evaluated the frequency of lymphatic drainage to the IM chain, the rate of SLNs that contain metastases and the clinical implications of IM LN metastases.
In this study we evaluated the frequency of lymphatic drainage to the IM chain, the rate of metastases in the IM SLN and the clinical implications of IM LN metastases.
5– 7, 12, 13 Apart from the effect of the injection technique we observed a higher frequency of lymphatic drainage to the IM LNs in patients with cranio- and caudomedially located tumors, as reported by others, 8, 14, 15 as well as an effect of age: IM SLNs were more common in young patients.
Although, we do not know the exact frequency of ectopic biliary drainage, the frequency of the ectopic biliary drainage was found to be 2% in our series.
This study was designed to identify the frequency of internal mammary drainage in patients undergoing sentinel lymph node (SLN) lymphoscintigraphy in a controlled clinical trial.
In our series, the frequency of ectopic biliary drainage is 2% (10 out of 400 ERCPs).
In addition, hernia patients had a higher frequency of primary percutaneous drainage after KPE (p = 0.025).
It has been reported that products consisting of pure calcium sulfate have a tendency to quickly dissolve [ 12] which, together with a low pH [ 23], leads to a high frequency of long term drainage [ 8] and subsequent wound complications [ 9].
Higher value of drainage frequency shows the high runoff.
The values of drainage frequency of sub-watershed area exhibits positive correlation with drainage density values of the area, indicating the increase in the drain population with respect to drainage density.
