2. 0 The indications for removing stones surgically
0 (1) economy and the personal convenience of the patient,
0 (2) associated disorders that require open operation,
0 (3) infected cases need- ing definitive and expeditious clearance of calculi,
0 (4) cases that have failed lithotripsy and endoscopic removal, and
0 (5) cases that for technical reasons cannot be managed by litho- tripsy.
0 open procedure is still indicated in cases of obstruction of a caliceal
infundibulum, the ureteropelvic junction, or the lumbar ureter and when the
volume and configuration of the stones contraindicate extracorporeal shock
wave lithotripsy (ESWL) or a percutaneous approach, such as with caliceal
stones larger than the renal pelvis.

4. Incission
0 a flank incision or an anterior
subcostal extraperitoneal incision
0 In children, a lumbotomy incision
may be effective
0 With a flank incision, raise the
kidney rest slowly to allow for
circulatory stabilization
sharply and bluntly above the ureteropelvic junction i
the hilum, working in the plane found directly on
adventitia of the pelvis. Russian forceps are useful if
fat is matted.

5. 0 Open Gerota's fascia laterally to provide
for later fatty enclosure of the pyelotomy.
0 After renal exposure, have the assistant
rotate the kidney toward the midline
with clamps on Gerota's fascia and the
perirenal fat or with a sponge stick.
0 Locate the ureter and encircle it with a
small Penrose drain. Continue the
dissection sharply and bluntly above the
ureteropelvic junction into the hilum,
working in the plane found directly on
the adventitia of the pelvis. Russian
forceps are useful if the fat is matted.

6. Simple Pyelolithotomy
0 Draw the hilum anteriorly with vein or
Gil-Vernet retractors placed in the lip
0 Incise the pelvis transversely in the form
of a U, starting with a hooked blade and
continuing with Potts scissors. Stay well
away from the ureteropelvic junction.
0 If small stones are present, pass an 8 F
infant feeding tube though the
ureteropelvic junction to prevent stone
migration. Stay sutures may not be
needed; they can tear the tissue.

7. 0 Withdraw the stones with forceps or
a Mixter clamp. If a large stone
adheres to the pelvic wall, free it by
passing a probe around it.
0 Irrigate the interior with water
through a cut-off Robinson catheter.
Use a Water-Pik.
0 Insert a flexible nephroscope if
concern remains about residual
adherent stones. Alternatively, close
the pelvis and inject coagulum (Step
4).

8. Coagulum Technique
0 Obtain two bags of thawed
cryoprecipitate (about 15 ml each),
and keep them at room temperature.
Add a few drops of methylene blue to
them in a pan. Draw the
cryoprecipitate into the 35-ml
syringe.
0 Obstruct the ureter by placing
traction on the encircling Penrose
drain. Insert an angiocatheter into
the renal pelvis, withdraw the stylet,
and drain the urine, estimating its
volume.

9. 0 Draw 1 ml of 10 percent calcium
chloride solution into the syringe
containing the cryoprecipitate
just before instilling the mixture
into the pelvis. Attach the syringe
to the angiocatheter, and inject
enough of the solution to fill, but
not overfill, the pelvis. Remove the
angiocatheter.

10. 0 Wait 5 minutes; then open the
pelvis with a U- shaped incision,
and gingerly extract the coagulum
with the stone. Sometimes
pressure on the kidney
parenchyma helps extraction.
After removing the clot, flush the
ureter with saline through the 8 F
infant feeding tube.

11. 0 Inspect the coagulum to be
certain it is intact. Thoroughly
irrigate the pelvis and ureter.

12. 0 It may be worth-while before closure to
pass a ureteral catheter or infant feeding
tube to the bladder to be sure that no
fragments are caught in the ureter, which
would promote prolonged postoperative
drainage.
0 Make a watertight closure of the pelvis
with a running 4-0 or 5-0 SAS with an
occasional lock stitch.
0 Suture a Penrose drain by the long suture
technique near the closure, being sure its
end does not touch the anastomosis.
0 Tack the edges of Gerota's fascia
together, and close the wound.

13. Extended Pyelolithotomy (Gil-Vernet)
0 Alternatives are
0 anatrophic nephrolithotomy
0 partial nephrectomy
0 Contraindications to this
intrasinusal approach
0 previous extended pyelolithotomy,
0 extremely intrarenal pelvis,
0 staghorn calculi in clubbed
calyces.
0 Expose the kidney as for simple
pyelolithotomy.
0 Proceed with complete mobilization
of the kidney to allow control of the
renal artery and to facilitate
roentgenography.
0 Have the assistant rotate the kidney
toward the midline.
0 Feel for the arterial pulsation, and
expose the renal artery. Draw a sling
around it with a right-angle clamp.
0 Try applying a bulldog clamp on it for
size and clearance.

14. 0 Dissect along the posterior
surface of the pelvis, entering the
renal sinus beneath the sinus fat
exactly on the adventitia of the
pelvis

15. 0 Excise excess fatty tissue. It is not
necessary to clear out all the fat;
the portion remaining cushions
the closure line.

16. 0 Separate the pelvis from the renal hilum and
peripelvic fat in the avascular plane by blunt
dissection.
0 Avoid the retropelvic artery, which is the posterior
branch of the main renal artery. It originates near
the superior edge of the pelvis and passes behind it,
sometimes outside and sometimes inside the hilum.
0 The scissors must be kept in close contact with the
adventitia of the pelvis. Even if there is considerable
reaction in the peripelvic fat, this plane remains
intact.
0 Insert special Gil-Vernet retractors over the whole
mass of peripelvic fat, and insinuate the corner of a
moist, opened 4 X 8 gauze pad to expose the bases
of the infundibula.
0 Have your assistant lift and rotate the kidney to
bring the pelvis into view. If the pelvis is extrarenal,
the assistant should relax pressure on the
retractors occasionally to allow flow through the
retropelvic artery.
0 If exposure is difficult, place a bulldog clamp on the
renal artery to reduce parenchymal turgor.

17. 0 Incise the pelvis in an open U shape
with a hooked scalpel blade and
Potts scissors. Design the cut to fit
the configuration of the periureteral
portion of the stone, keeping well
away from the ureteropelvic junction.

20. 0 Grasp the stone with Randall forceps. Gently
rock and rotate it to extract its caliceal
extensions.
0 Extricate the shortest branch first.
0 If absolutely necessary, fracture the neck of one
or more of the branches and remove the
clubbed ends via transverse nephrotomies.
0 Often an infundibulum can be dilated with
forceps sufficiently to allow an extension of the
main stone to be extracted.
0 If the renal hilum is large enough, a vertical
incision along the involved infundibulum (cali-
cotomy) may assist in the removal of large
caliceal stones.
0 Remove the stone and fit the pieces together to
be sure all were retrieved.
0 Send the stone for culture and analysis.

21. 0 Inspect the interior of the calyces,
using a flexible nephroscope if
necessary, and remove any remaining
calculi, usually with stone forceps or
Mixter clamp.
0 If the stones are too large to pass
through an infundibulum, gently
dilate the opening with a clamp.
0 Try not to use a finger or high
pressure. Irrigate each calyx in turn,
using a large syringe and a cut-off 18
F red rubber catheter.

22. 0 Make a radial nephrotomy over
clubbed caliceal stones too large to
extract through the infundibulum.
0 Locate the site of the stone by
pushing it toward the capsule with a
clamp or finger in the infundibulum
and palpating it through the cortex.
0 If it cannot be felt, probe for it with a
milliner's needle.

23. 0 Sharply incise the capsule circumferentially
for a distance equal to the diameter of the
stone; then bluntly separate the kidney
parenchyma down to the stone, which is
supported by a clamp or finger in the
infundibulum.
0 Extract the stone with forceps inserted into
the nephrotomy. If the cortex is thick, it is
helpful to place a bulldog clamp on the renal
artery to soften the kidney long enough to
locate and remove the stone.
0 If these manipulations are to be prolonged,
cool the kidney and give mannitol
intravenously. Irrigate the calyx thoroughly
with saline.
0 Avulsion of the ureteropelvic junction is
possible. With a segment made ischemic by
chronic impaction of a relatively large stone,
avulsion can occur during dissection. Repair
and intubation are necessary), even though
the tissue has the quality of wet paper.

24. 0 Close the nephrotomy with 3-0 CCG mattress su-
tures over fat bolsters.
0 If the pelvis lies principally inside the sinus,
exposure can be improved by inserting a grooved
(Gouley) sound along the outside of the inferior
pelvis and lowest calyx and out through the
lower-pole parenchyma. Cut into the groove and
divide the renal cortex. Alternatively, pass
successive pairs of sutures, tie them, and cut
between them.
0 Perform radiography
0 A straight milliner's needle thrust through the
cortex can be useful to locate residual stones, and
two needles provide a landmark on the
roentgenogram.
0 Intraoperative nephroscopy and sonography are the
best techniques to detect and clear remaining
stones.
0 Coagulum can be used if the pelvis is closed first.
0 Pass an 8 F catheter down the ureter to be sure it
is clear.

25. 0 A nephrostomy tube made from perforated
silicone tubing may be brought out through
the lower pole but is necessary only when
stone removal is incomplete and irrigation
postoperatively with hemiacidrin (Renacidin)
must be resorted to.
0 Close the pelvis with a running 5-0 SAS,
occasionally locked.
0 If reaching either end of the incision for
suturing is difficult, start and finish the closure
at convenient sites because the parenchyma
falls over the suture line and prevents leakage.
Irrigate the wound copiously.
0 Tack a Penrose drain near the pelvis with the
long suture technique, although urinary
leakage is unusual. Fasten Gerota's fascia over
the kidney with 3-0 plain catgut sutures.
0 Close the wound
At a secondary operation, the kidney is found firmly attached
to the transversalis fascia and is readily entered inadvertently.
Identify the capsule early, and dissect it carefully from the
fibrous bed. Enter the sinus anteriorly and inferiorly, at a site-
distant from that for the initial pyelolithotomy.
