The Pediatric Urology Service at MassGeneral Hospital for Children provides state-of-the-art urologic care ranging from very simple circumcisions to the most complex urinary and genital anomalies encountered in children from birth to young adulthood.

Conditions Treated

Through a number of specialized clinics, we provide comprehensive diagnostic and therapeutic services for the broad spectrum of surgical diseases affecting the urinary and genital tracts:

  • Vesicoureteral reflux (including minimally invasive endoscopic treatment with Deflux), urinary tract infection
  • Voiding dysfunction, enuresis, urinary incontinence
  • Neurogenic bladder
  • Obstructive uropathies: congenital hydronephrosis, congenital megaureter, ureteral duplication/ureterocele, posterior urethral valves
  • Prenatal consultation for antenatal hydronephrosis and other obstructive uropathies
  • Inguinal hernia, hydroceleundescended testicle (including laparoscopy for diagnosis and treatment of nonpalpable testis), varicocele
  • Hypospadias
  • Disorders of sex development, genital reconstruction in males and females
  • Bladder exstrophy, cloacal exstrophy, epispadias
  • Anorectal malformations: imperforate anus and persistence of the cloaca
  • Complex urinary tract reconstruction (undiversion, bladder augmentation, incontinence procedures)
  • Prune belly syndrome, posterior urethral valves
  • Ectopic ureter/ureterocele
  • Hidden penis/webbed penis
  • Ectopic kidney, horseshoe kidney, crossed fused ectopia
  • Multicystic dysplastic kidney
  • Testicular torsion
  • Tumors: Renal, retroperitoneal, bladder, prostate and testicular
  • Trauma
  • Renal transplantation including minimally invasive nephrectomy for organ donation
  • Kidney stones

Minimally Invasive Pediatric Urology

Endoscopic treatment of vesicoureteral reflux: the use of a tissue bulking agent, in particular dextranomer/hyaluronic acid, has resulted in a minimally invasive alternative to the open surgical and medical treatment of vesicoureteral reflux. We have been performing this technique as an outpatient procedure in selected patients with a high success rate.

Laparoscopic surgery: laparoscopic procedures have resulted in faster recovery time, less pain and better cosmetic results. We are performing laparoscopic procedures in an increasing number of conditions.

Disorders of Sex Development Clinic

Our clinic is backed by more than 40 years of experience in this field, beginning with the seminal contributions of William Hardy Hendren, MD, and Patricia Donahoe, MD.

Jason Michaud, MD, PhD, has significant interest and experience in the surgical treatment of these conditions. Research work produced by the Pediatric Surgery Research Laboratories, headed by Dr. Donahoe and David MacLaughlin, PhD, has resulted in numerous publications dealing with the molecular mechanisms causing intersex abnormalities. Based on this combination of clinical and research experience, Mass General for Children has become a recognized referral center for ambiguous genitalia. In our clinic, patients are evaluated by a multidisciplinary team of pediatric urologists, pediatric endocrinologists, geneticists, psychiatrists and basic science investigators, who strive to provide our patients and their families with state-of-the-art medical and surgical treatment.


Clinic for Complex Reconstructive Pediatric Urology

This clinic is devoted to the management of complex urological and surgical cases such as imperforate anus, persistence of the cloaca, bladder exstrophy, cloacal exstrophy, urinary diversions and undiversions, Prune Belly Syndrome, and tumors of the genitourinary system.

The complexity of these conditions requires the involvement of highly experienced surgeons, with a thorough understanding of its embryology, anatomy and resulting functional problems. Our surgeons use their background and experience in pediatric urology and pediatric general surgery to provide their patients with state-of-the-art surgical treatment.

Hypospadias Clinic

Hypospadias is a very common condition, in which the male urethral opening (urethral meatus) does not reach the tip of the penis. Hypospadias occurs in about 1 in 200-300 male births and presents in a broad clinical spectrum. Surgical repairs require considerable experience and the use of a meticulous technique to achieve good results. 

The vast majority of cases can be repaired in a single-stage procedure using local tissues. The use of newer surgical techniques, fine absorbable suture material and visual magnification has significantly improved the success rate in hypospadias surgery. Complex cases might require the use of grafts; these may be taken from sites such as the buccal mucosa, bladder mucosa or skin.

Our pediatric urologists run a busy hypospadias clinic and when indicated, our patients are evaluated by a team expanded to include pediatric endocrinologists and geneticists.

Preparing for Your Appointment

The family should bring relevant medical records, test results, and X-rays to the appointment to avoid duplications. A recent urinalysis and urine culture is convenient in cases of urinary tract infection.

Instructions for specific tests may be provided when an appointment is scheduled.

Treatment is provided in close communication and cooperation with the patient's referring physician.

Patient Resources

The Pediatric Urology team at MGfC has developed a variety of resources for pediatric patients of all ages with urologic concerns and their families. View the full resource list here.

Infant Spinal Anesthesia Program

The Infant Spinal Anesthesia Program at Mass General for Children provides spinal anesthesia, also known as a spinal block, as an option for newborns and babies undergoing certain procedures of the lower body (any area of the body below the belly button).

Spinal anesthesia is a technique where the anesthesiologist administers an anesthetic into the spinal fluid with a small needle. It causes the patient to become immobile and numb from the waist down, without losing consciousness. In many cases, the infants are able to take a nap naturally after the onset of spinal anesthesia.
