PCNL in supine position is safe, effective and suitable for the patients. It offers the potential advantages of better urethral access, less patient handling, needing drape only once, ability to perform simultaneous PCNL and ureteroscopic procedures, better control of the airway during procedures, thus reducing over-all operative time compared to traditional prone position and performing PCNL while the surgeon is sitting. It may be considered for most patients requiring PCNL.

We conducted a text message-based intervention for weight management over three months by two months intervention and one month wash-out period. In a quasi-experimental study with control (n = 40) and experimental group (n = 40), 80 overweight and obese employed women were entered. Participants were recruited via announcement. All subjects attended a face-to-face information session and received a booklet that contained food calorie chart and strategies and recommendations for weight management. The experimental group received text messages (SMS) about weight management twice a day for two months, in addition to the information and the booklet which they had received in the information session. Also, the experimental group was instructed to weekly self-weight and to send the data to the principle researcher. All subjects were measured for baseline and secondary weight in a standardized manner by a nurse, and the data were compared between the two groups. Experimental group lost more weight than the control group (1.5 kg difference, P = 0.018). Text messaging seems to be an effective channel of communication for weight management in Iranian overweight and obese women. The clinical trial registration number is IRCT201204029360N1.

Complications, operative time, and the length of hospitalization in selected patients undergoing tubeless PCNL were all lower than those seen in the standard group. Tubeless PCNL was thus found to be safe and effective, even in patients with staghorn stones.

In the COVID‐19 pandemic, the overlap of clinical features between other viral infections makes a reliable diagnosis difficult in the initial stage of illness. We describe a confirmed case of CCHF in Tehran Province during this year, who was first misdiagnosed as COVID‐19 infection.
