[|Human|] Hi ... My father was diagnised with a 1 cm Kidney stone. He took up the operation which was not very successful. The tube which was sent inside was unable to reach the stone in order to blast it because the passage was narrow. Hence the doctor have placed a smaller tube so that the passage becomes wider over a 2 -3 week period and they can perform the operation again. Now the querry is we learnt that there is  a method called LITHROTRIPSY which is available in other hospitals . Can we go for it since it looks like a less painful excersise ...2. Should we wait for 3 weeks and the 3rd querry.. Will a foreign tube being inside the uretral affect in some way.. Kindly advise us
[|AI|]  1st of all 1 cm kidney stone needs treatment. Usually ESL is Enough if the HU units are less than 1000 on Your 1st question, since there is a Ureteral stent already, you can go ahead with ESL or lithography as you said. Generally, 3 sittings are advised without any problems. And no there is absolutely no problem if there's stent inside. Only thing is, patients may complain of pain especially when passing urine. And yes, it's better to wait for 3 weeks. Access and then go ahead with lithography. Give some time for the patient and explain he need not worry. Hope this helps.
