Laparoscopic Urologic surgery, is a part of the curriculum of Minimal Access Surgery, and requires lot of skills and patience. All new surgeons carrying out Basic Laparoscopic surgery should aim at also doing Lap. Urological surgeries, which has a steep learning curve, but with with excellent outcomes.
3. History of Lap. Urology
• The first laparoscopic Nephrectomy was performed in 1990 by
Clayman
• The procedure had an operative time of seven hours and
required a 1-unit transfusion and a six-day inpatient hospital
stay.
4. Challenges of Uro –lap. surgery
•Technically, more demanding
•Specialized team
•Slightly more expensive, use of consumables
•Advantages outweigh the challenges
5. Laparoscopic Surgery
•Key hole surgery
•Latest development of Urology
•Obvious advantages over conventional open surgery
•Smaller wound
•Less pain
•Quicker recovery, discharge, early return to work
6. Laparoscopic Urological Surgery
•Revolutionary development in last 2 decades.
•Experienced centres
•Improves Patient’s peri-operative quality of life
•Provides excellent view due to magnification – less tissue
trauma & minimal blood loss.
7. Approaches
The 3 three commonly used approaches are
1. Transperitoneal approach
2. Retroperitoneal approach
3. Hand assisted approach
8. Transperitoneal approach
•Wider availability
•Working space
•Better identification of important landmarks
•Intestinal Injury ?
Retroperitoneal approach
•Restricted rapid access
•Renal pedicle identification.
•Reduce the incidence of ileus
•Injury to the intraperitoneal contents
Hand assisted approach
•Improved tactile feedback
•Bridge between open surgery
•Lap Gelport TM
•Lap Disc TM
9. Laparoscopic urological procedures
• Commonest procedures performed :-
Ablative Procedures:
a) Simple nephrectomy
b) Partial nephrectomy
c) Renal cyst marsupilisation
d) Radical nephrectomy
e) Radical cystectomy
f) Radical prostatectomy
Reconstructive Procedures:
a) Pyeloplasty
b) Lower ureteric reconstructions
c) Boari flap reconstruction
d) Ureteric reimplanation/Psoas hitch
e) Ileal ureter
f) Orchipexy
g) Donor nephrectomy
10. Simple Nephrectomy
•Non functioning
•Pre renal transplant nephrectomy
(A) – Transperitoneal approach
Pneumoperitoneum - open technique or closed technique.
Ports are inserted in a strategic manner.
Preoperative CT Scan)” if done helps in determining the location of the kidney
and deciding the location of port placement.
Other parameters which determine the site of port placement are extent of
truncal obesity and body mass index (BMI).
11. Positioning
• Lateral decubitus position
• Near the edge of the table
• Lower limb is flexed
Technique
• Left side colon is reflected
• Iliac bifurcation
• Superiorly the splenorenal
• Renocolic ligaments
• Identify the ureter
• Gonadal vessels
• Ureter is lifted
• Psoas landmark
12. (B) – Retroperitoneal approach
Gaur etal
15mm incision petit triangle
Lumbodorsal fascia
Balloon dilator
(C) – Hand assist approach
Insert a non dominant
Hand assist device is inserted
Right lower quadrant midway between umbilicus and anterior
superior iliac
13. Laparoscopic radical Nephrectomy
•T2 & T3a tumors.
•T1 tumors contraindicated with IVC thrombus
Technique
•Transperitoneal
•Lumbar & adrenal veins are doubly clipped & cut.
Results
•Advantage short hospital
•Low analgesia
•Comparable
•Open laparoscopic approach is a standard of care in T1 & T2.
• Renal thrombus is feasible
14. Laparoscopic partial nephrectomy
•Small renal masses
•Indications lesions in a solitary kidney
•Bilateral renal lesions
Technique
- Pneumoperitoneum
- Ports similar to simple nephrectomy
- Ureteric catheter placed per-urethrally - to instill methylene blue
- Identify the pelvicalyceal system prior to suturing
- Colon reflected and the ureter is lifted off the psoas muscle
- Dissection proceeds to the renal hilum
- Renal hilum dissected & satinsky applied
- Once renal tumor is cut with cautery or harmonic
- Preferred scissors for excising the tumor should be with wide jaws.
- Pelvicalyceal system is closed followed by the cortical defect
- An indwelling ureteric catheter or alternatively a double J stent is placed for 48hours.
15. Pyeloplasty
•RGP prior to positioning the patient
•5Fr pigtail catheter is inserted into the pelvicalyceal system
Technique
•30 degree Scope - pelvis is identified bulges out
•Dismembered Anderson hynes Pyeloplasty is preferred crossing vessel is
suspected
•Y-V plasty is preferred
The important steps of this procedure are
•Pyelotomy
•Spatulation of the ureter
•Pyelotomy is closed a 3-0/4-0 vicryl
•‘V’ stitch as anterior layer easier step to start , followed by posterior layer.
16. Donor Nephrectomy
Do no harm to the donor is the dictum
Technique
•Port placement mirrors that of simple nephrectomy
•CT angiography plays a pivotal role for strategic port placement.
•Ureter should be lifted of the psoas “in toto” as an ureterogonadal
packet.
•Dissection of the artery should be a thermal and should be kept to
the minimum.
•Topical papvarine instillation on the vessel helps in relieving spasm
•Upper pole should be separated from the spleen securing the adrenal
vein
•Graft should be adequately perfused by intravenous infusion of
mannitiol and furosemide prior to retrieval
•Retrive the graft through a pfannesteil incision
17. Laparoscopic ureteral reimplanation
Supine position a 11mm trocar for camera insertion umbilicus
Ureter is lifted transected as distally as possible
The bladder is filled with 200ml saline
Lateral and anterior peritoneum incised a boari flap is preferred
Spatulated ureter and the bladder flap are anastomosed in a tension free
manner with 4-0 polygalactin sutures
A stent is kept indwelling for 6weeks after the surgery
Laparoscopic stone removal
Procedure performed transperitoneal or a retroperitoneal approach
Placement of a stent ureteric catheter
Ureter lifted of the psoas
The ureter is slinged
Using a cold knife the ureter is incised
Spoon may be used for retrieving the stone
Stone may be entrapped in a bag for removal
Ureterotomy is closed with a 3-0 absorbable suture and a drain is placed.
19. Robot assisted laparoscopic urology
•Prostatectomy ,Pyeloplasty, Nephrectomy & Ureter reconstructions
•Donor nephrectomy
•Adrenalectomy
•Advantages:
•Robotic platform Da Vinci Si
•High definition visual magnification
•Better range of motion
•Additional arm for retraction
•A unprecedented range of accuracy and dexterity
•Its increased range of freedom
•Property of “motion scaling”
•Procedures requiring intracorporeal suturing
•Small spaces pelvis
•The cost benefit ratio is likely to be a driving force in further development and
application of this technology
27. Laparoscopic Prostatectomy
5 small incisions
•Completely mimick all the principles
of open surgery
•Extraperitoneal approach, avoiding
contact with intestine
28. Laparoscopic Prostatectomy
•4-5 hours surgery
•Less blood loss, minimal blood transfusion
requirement
•Magnification allowing more accurate
dissection and preservation of continence and
erection
•Hospital stay of 2nights, early removal of
urinary catheter.
29. Laparoscopic radical prostatectomy
• Inverted fan shaped manner
• Endopelvic fascia incised
• Dorsal vein secured
• Vas deferens
• Dissected secured hem-o-lok
• The lateral detrussor pillars are secured with
clips
• The urethra is dissected be to gain maximum length of the urethra
• Posterior reconstruction stich “Rocco”
• The van velthowen technique (bidirectinal running suture) technique of
3-0 monocryl
• Satisfactory oncologic outcome
33. What is new in laparoscopy in urology?

36. Summary
•Surgery is moving towards minimally invasive surgery.
•Urology - ESWL, Endoscopy, Percutaneous & Laparoscopy.
•More than one or a combination of MIS modalities may be used.
•Endoscopic and Per cutaneous procedures almost treat all the
urolithiases, prostatic and bladder diseases.
•Robotic Surgery is the future for dealing with Prostate and
Bladder.
