MD UROLOGY AND ANROLOGY

4. • Symptomatic obstruction (recurrent flank
pain, UTI) requires surgical correction
using a pyeloplasty, according to the
standardised open technique of
Hynes and Anderson [492]
• There does not seem to be any clear
benefit of minimal invasive procedures in
a very young child but current data is
insufficient to defer a cut-off age

7. • Indications
• Technical aspects
• Outcomes and Cost

8. • Open pyeloplasty is the standard
surgical TTT for the PUJO
• Universal treatment for universal
pathology

9. LP
• Technically challenging patients [morbidly
obese , children less than 1year]
• failed open pyeloplasty [perinephric
scarring and the potential for
devascularization of the proximal ureter]

11. TECHNICAL ASPECTS

• Magnification
• Traction sutures
• Prestenting
• The surgical procedure and judgment on
renal parenchyma or pelvic dimension
• Excellent assessment of secondary
pathologies
• Training and learning curve

17. Traction sutures and orientation
• Traction sutures are crucial part of
pyeloplasty
• In open pyeloplasty they are easily
done
• Orientation and good judgment on the
dimension

• Dissection and full mobilization difficult owing to
the decompression of the renal pelvis by the
stent.
• The stent can be cut accidentally [migration]

The approach to repair may best be
based on family preference for incision
aesthetics and surgeon comfort with
either approach, rather than more
classically objective outcome measures

• Operative time was longer for minimally
invasive pyeloplasty compared to open pyeloplasty
• Laparoscopic and robotic pyeloplasty had longer
median operative times (240 minutes, p <0.0001 and
270 minutes, p <0.0001, respectively].
• Length of stay was equivalent across all procedures.
