Wish you all be healthy in the threat of pandemic corona virus infection around the world! Quarantine or social distancing has been recommended for all. To thank the support from authors, reviewers and editors, we continue the editorial work to publish the March–April issue on time. Hence, read urological science at home could be the best choice for you who should stay at home after hospital work!

Urethral stricture has been noted for many years. Chu YC et al. reported good success rate (90%) in primary anastomosis for stricture <3 cm and buccal mucosal graft urethoplasty for stricture >3 cm. Although the case number is small, only 10 in each group, the outcome is promising. Chung CH, et al. reported the classical approach: Direct vision internal urethrotomy (DVIU) in 232 patients. The success rate of the first urethrotomy procedure was 0%, the second attempt 53%, the third one 40%, and the fourth and fifth procedures 39% and 18%. Patients who had anterior urethral stricture related to previous surgery (surgery-related) had a better outcome (success rate, 87.3%) than patients with strictures stemming from other causes (P = 0.003). One may propose that DVIU may be good for a short stricture related to surgery. For a difficult case, direct anastomosis may be the choice if stricture segment is shorter than 3 cm, while buccal mucosal graft (BMG) is recommended in cases with a stricture segment >3 cm.

Advancement of managing urolithiasis continues. In this issue, Lee YC, et al. reported “Tubeless minipercutaneous nephrolithotomy for treatment of renal and upper ureteral stones of ≥3 cm in diameter”. Less bleeding, smaller wound, and quicker recovery were found in this technical advancement. Chen YC, et al. reported “A Comparative Study of Simultaneous Supine Percutaneous Nephrolithotomy (PCNL) with Retrograde Ureterolithotripsy and Semi-Rigid Ureteroscopic Lithotripsy (URL) in the Management of Large Proximal Ureteral Calculi.” Combining PCNL and URL in a supine position reduced wound size and complication, while kept success rate.

Thanks to knowledge and technological advancement, both urethral stricture and urolithiasis have better surgical outcomes with less morbidity! More topics are reported in this issue: Early or late repair of urethral disruption, and comparisons between open and single port extraperitoneal repair of hernia.
