This is a well-written case report on the intrathoracic double J stent migration
through a reno-pleural fistula. The authors nicely presented the case and their
management. 
Herein are my questions and comments: 
1. The word "case report" should be included in the title. 
2. The past medical and surgical history of the patient, specially any hx of GU
procedures, should be included. 
3. The authors should add more details about the patient's cervical cancer (e.g.,
initial symptoms, time of diagnosis, clinical staging, any imaging showing the
pelvic disease and the associated hydro). 
4. What was the timeframe between PCN and JJ placement? Any antegrade
nephrostography done at time of PCN placement/removal? 
5. The authors should elaborate more on the PCN technique (i.e., imaging
modality and approach). Was the PCN done via a supracostal approach?! If yes,
please discuss the reason. If no, the respective statement is the conclusion should
be deleted. 
6. What was the reason for a delay in performing PCN after thoracoscopy? If
there was no PCN or JJ in the aforementioned week, the fistula would continue
draining into the chest.
