Minimally Invasive Surgery & Robotic Assisted Surgery

What is Minimally Invasive Surgery (MIS)?

Minimally invasive surgery (MIS) is surgery done through little incisions using small surgical tools and telescopes. Some of the benefits of MIS are less surgical pain, less scarring, smaller incisions, quicker recovery with shorter hospital stays, and an earlier return to normal daily activities.

Surgeons who perform this type of surgery have undergone extensive specialized training, however they also know how to perform the same operations in the traditional open manner.

Newer technologies, such as robotic-assisted surgery, offer the potential for minimally invasive surgery to continue to improve and offer even more benefits to pediatric patients.

Minimally invasive surgery is not appropriate for all individuals. Your surgeon will be able to tell you in which cases it may be the best choice.


What are the types of MIS?

Laparoscopic Surgery

This is a common form of MIS in which small instruments and a telescope are passed through the body wall. The instruments are used by the surgeon who controls their movements, while watching them on a video screen. This form of MIS has been used widely in adults and children. In Pediatric Urology, this usually involves operations in the abdomen including surgery of the kidney, ureter, bladder and reproductive organs.

Endoscopic Procedures (Endourology)

This type of MIS typically involves using a scope passed through the body’s natural openings.  In Pediatric Urology this mainly involves the structures of the urinary tract.  These procedures include cystoscopy (looking inside the bladder), ureteroscopy (looking inside the ureter and kidney) and percutaneous nephroscopy (looking inside the kidney, by way of a small incision in the skin).

Endoscopic procedures in Pediatric Urology are used to treat disorders such as kidney and bladder stones, UTIs and vesicoureteral reflux, blockages of the urinary tract and for diagnostic purposes.

Robotic Assisted Surgery

Pediatric Robotic Surgery is one of the most exciting and promising areas in the field of minimally invasive surgery.  Robotic technology make it ideally suited for use in a number of complex Pediatric Urology procedures.

The da Vinci® Surgical System provides surgeons with an alternative to both traditional open surgery and conventional laparoscopy, putting a surgeon’s hands at the controls of a state-of-the-art robotic platform. The da Vinci System enables surgeons to perform even the most complex and delicate procedures through very small incisions with unmatched precision.

For the patient, benefits may include:

  • Significantly less pain
  • Less blood loss
  • Less scarring
  • Shorter recovery time
  • A faster return to normal daily activities
  • And in many cases, better clinical outcomes


In November of 2011, Dell Children’s Medical Center became only the second free standing children’s hospital in the state of Texas to acquire a surgical robot, specifically the fourth-generation da VinciSi HD Surgical System from Intuitive Surgical®. The Si incorporates a number of new features that enhance the operative experience for the surgeon, operating room team, and patient.

Dr. Danielle D. Sweeney was the first pediatric surgeon in Central Texas to be certified on Dell Children’s Medical Center’s new robotic system. Before the arrival of the  robot at Dell Children’s Medical Center, Dr. Sweeney performed robotic pediatric urologic procedures on Seton Medical Center Austin’s da Vinci robot. Under the direction of Dr. Danielle Sweeney the Robotic Surgery program at Dell Children’s Medical Center is growing to include other medical specialty groups. Dr. Sweeney is an expert in the field of MIS surgery in the pediatric population, and Children’s Urology is excited to offer robotic surgery options in central Texas.

Dry Solutions: The Center for Voiding Dysfunction

The Center for Voiding Dysfunction at Children’s Urology is a comprehensive clinic devoted to helping children and their families overcome a wide variety of urinary issues. These include daytime or nighttime wetting (enuresis), urinary urgency, frequency and pain, and recurrent urinary tract infections.

What is Voiding and Enuresis?

Voiding dysfunction is a term used by doctors and nurses to describe abnormal emptying of the bladder. Enuresis, also a medical term, is a type of voiding dysfunction that refers to involuntary urination or “wetting.” Most children have control of their bladders by age four for daytime control and by age six for nighttime control.

Evaluation and Treatment

There are many reasons why children have wetting accidents, urinary pain or recurrent infections. Sorting out the issues and developing a plan to make them stop is our team’s goal for your child.

A clinician will do a thorough evaluation and physical exam during your visit. We also use tools such as voiding and elimination diaries to help us to get a better sense of your child’s bathroom use and how often your child has accidents.  For children with recurrent UTIs, we work closely with their other medical providers to tailor a plan that is appropriate for the child and family.

After your child’s evaluation, we may recommend a variety of different management plans or tests.  This may be as simple as changing your child’s bathroom patterns and diet, or more involved like pelvic floor therapy,  biofeedback  or our Pediatric Gastrointestinal (GI) Care Clinic.

Comprehensive Therapy

The Team

The Center for Voiding Dysfunction is under the direction of Dr. Leslie T. McQuiston and is managed by Amanda Ramos Hodge, RN, CPNP.

To make an appointment, please call 512-472-6134 or request an appointment online.

Center for Advanced Reconstructive Urologic Surgery

surgeonThe Children’s Urology Center for Advanced Reconstructive Urologic Surgery is under the direction Dr. Jose Cortez who was the first board certified Pediatric Urologist in Central Texas.  He performed the first bladder exstrophy closure in Central Texas, as well as many other complex reconstructive procedures.   He is an expert in the management of complex congenital anomalies and the advanced anatomic reconstruction needed to manage these conditions.  This includes repairs for complex hypospadias, bladder exstrophy, cloacal exstrophy, epispadias and disorders of sex development.  The Center also works with children who have undergone failed procedures and are seeking other options for reconstruction.

The Children’s Urology Center for Advanced Reconstructive Urologic Surgery is committed to following our patients throughout childhood, adolescence and as adults as needed.  After surgical repair, we closely monitor your child’s development, growth, and overall health, with emphasis on the urinary tract.  We also provide a multidisciplinary approach by working closely with other pediatric experts to ensure that your child is getting the most comprehensive and complete care.

To make an appointment please call 512-472-6134 or request an appointment online.

Center for Urologic Prenatal Counseling

The expectant birth of a child can be an exciting time for many families, however when there is a potential medical problem with the baby those emotions may turn to fear and anxiety. Our goal at The Children’s Urology Center for Urologic Prenatal Counseling is to offer support and to educate families whose children are diagnosed with a congenital urologic issue.

Our physicians meet with families before the child is born in order to formulate a management plan for the baby and to discuss the needs of the family. This often includes coordinating care with the mother’s obstetrician, the baby’s pediatrician and in some cases the neonatal intensive care units throughout Central Texas. We also help coordinate care with other pediatric specialists as needed. Our center will help arrange urologic follow-up and imaging tests after the baby is born.

To make an appointment please call 512-472-6134 or request an appointment online.

Kidney Stone Center

Kidney stones are becoming more common in children, which is why Children’s Urology has developed a comprehensive kidney stone program for the children of Central Texas. According to the National Institutes of Health (NIH), 1 out of every 10 people will develop kidney stones during their lifetime.  The management and evaluation of kidney stones can often be complex particularly in children which is why you want a pediatric expert to be managing your child’s care.  Children are not little adults!

At Children’s Urology we take a multidisciplinary approach to treating kidney stones in children.  Not only are we experts in the surgical treatment of this condition in children, but we also manage dietary and nutrition concerns to help prevent new stones from forming.  Each child has an individualized treatment plan, which includes stone and urine analysis and radiographic imaging. Referrals to other pediatric specialists such as pediatric nephrology, pediatric endocrinology, or pediatric dieticians are coordinated through our office.

In terms of surgical treatment options, our physicians are experts in the laser treatment of stones, breaking stones using shock waves, as well as other minimally invasive techniques using the surgical robot.

To make an appointment please call 512-472-6134 or request an appointment online.

Spina Bifida and Neurogenic Bladder

Spina Bifida and Neurogenic Bladder

Spina Bifida is the most common cause of a neurogenic bladder in children. Our providers specialize in all aspects of medical and surgical care for patients with spina bifida.

Under the direction of Dr George M. Seremetis, patients are seen in the multidisciplinary Spina Bifida Clinic, located in the Specialty Care Center at Dell Children’s Medical Center.  At your child’s initial evaluation diagnostic testing and a complete physical exam will be performed to establish a comprehensive and individualized treatment plan, which may include UTI management, bowel program or institution of clean intermittent catheterization.

Our team works closely with the other medical team members such as neurosurgery, orthopedics, PT/OT, SW and equipment specialists, to round out the care of the patient, in addition to the nurse coordinators who manage and coordinate all aspect of the child’s care.

Our physicians also oversee the Urodynamic Testing Center at Dell Children’s Medical Center, taking the lead role in performing and interpreting this testing modality.

More information please visit the Dell Children’s Medical Center Spina Bifida Clinic home page.
