Dr. Laurence S. Baskin is a urologist and an expert in genital development and reconstructive surgery. His focus is on providing care for the spectrum of pediatric urological conditions, including undescended testicles; blocked kidneys and ureters; prenatal urinary tract obstruction, such posterior urethral valves; adolescent varicoceles (enlarged veins in the testicles); differences in sex development ; cancers of the genital and urinary organs; and disorders that require urinary tract reconstruction. He founded the UCSF Center for the Study and Treatment of Hypospadias to advance care for this birth defect of the penile urethra (the tube through which urine is voided). Baskin has written extensively on hypospadias and genital reconstruction, lectures extensively on these topics and has produced videos on numerous surgical techniques. His laboratory focuses on investigating the causes of pediatric urological diseases – both those present at birth and those that develop later – to advance the prospect for cures. The lab looks specifically at how cells communicate during normal and abnormal development and at the effects of abnormal environmental exposures during pregnancy. Baskin earned his medical degree at the David Geffen School of Medicine at UCLA. He completed a general surgery residency at UCSF, followed by a fellowship in pediatric urology at Children's Hospital of Philadelphia. Baskin is a fellow of the American College of Surgeons and American Academy of Pediatrics.
