Brief Answer: Please find detailed answer below Detailed Answer: Hi XXXXXXX Hope you are doing great. Thanks for writing in with a new query. I do work in close association with substance abuse rehabilitation patients and have made academic presentations on various occasions on the topic. Concerning cocaine use and health complications, the ones most commonly seen are pulmonary edema (water in the lung tissues causing swelling) and pulmonary hemorrhage (bleeding in the lungs) which can be seen in any route if drug intake. Nasal intake (sniffing) causes nasal septum perforation (small holes in the nasal septum) and irritation of upper airway causing epiglottitis, sinusitis and in the lungs, aspiration and bronchitis. Also non specific heavy drug abuse (intravenous route) for a long duration can cause bacterial pneumonia, pulmonary embolism, septic emboli, empyema, pneumothorax, upper lobe bullous emphysema as far the lungs are concerned. Having said the above, I do not see any of the lung findings closely related to cocaine in your scan. At the same time you never know if changes will occur in the near future with continued use. Since I believe that you have only done sniffing, serious effects have still not appeared. Hope I have been able to answer your query. Please do write back if you have any doubts. Regards, Dr.Vivek

Brief Answer: Please find detailed answer below Detailed Answer: Hi XXXXXXX You are welcome and thanks for writing back. I would like to re assure you that any information shared is purely confidential to the best of my knowledge and I respect your privacy. Further you may put in an email request to WWW.WWWW.WW NOT to share any of your information on any public domain. Before replying to you medical query, I would like to inform you that I got a call from WWW.WWWW.WW requesting me to answer query Id 80540 placed by you dated 9 Nov 2013. Subsequently I informed them that I have been replying to your queries on another thread, which is this thread. If you choose, you might close query Id 80540 by contacting customer care at WWW.WWWW.WW I have done a review of recent medical literature on queries made by you and found that the possible normal hospital stay for a radical nephrectomy is about 6 days. It is confirmed that your tumor is a slow growing one and contained within the right kidney with slight involvement of the collecting system. In such renal cancers, there is possibility of development of tumor thrombus in the inferior vena cava (a great vein in our body). I suppose this is what you mean by asking invasion into vessels. This occurs in few patients and IVC tumor thrombus is a complicating factor that occurs in 4% to 10% of patients with renal cell carcinoma. I think you are one of the lucky ones who doesn't have it. The link for the article is as follows WWW.WWWW.WW Concerning metastasis and IVC thrombus, data shows, of the patients 23% had an isolated lung metastasis, and 53% had metastasis in the lung and at other sites. The remaining patients had involvement primarily at non pulmonary metastatic sites, including lymph node in 38%, soft tissue in 13%, liver in 29% and bone in 10%. So metastasis is more of a chance occurrence than concurrent vessel invasion. Hope I have been able to answer your query. Please do write back if you have any doubts. Regards, Dr.Vivek
