6hrly) & continued after Culture report.
-Analgesic-antipyretics(Inj.Paracetamol)

12. Nephrology,Diabetelogy & Cardiology
consultations
On Retrograde Uretero-pyelogram, No filling
defects or contrast extravasation seen.
Lt.DJ Stenting done to control symptoms(13-07-
14)

13. -Symptoms(Fever,Pain,Vomiting) persist
despite Lt.DJ stenting.
-Persistent hypokalemia &
hypomagnesemia despite correction.

14. Repeat USG Abdomen (14-07-14)
-Lt.Kidney enlarged, hypoechoic & edematous.
Fullness of pelvicalyceal system with thickening of
renal pelvis.DJ Stent in-situ. No e/o abscess or
collection.

15. On account of non-resolution of symptoms & USG
report, it was decided to consider external urinary
drainage through Lt.PCN.
USG Guided Lt.PerCutaneous
Nephrostomy(PCN) done on 15-07-14.
Drastic improvement in pts'.symptoms &
clinical condition.(Pain,Vomiting & fever
subsided.)
Diuresis ensued(s/o relief of obstruction);
managed appropriately using fluid & electrolytes.

18. DISCUSSION
URETERAL STENTS :
Ureteral stents are a mainstay in the urological
armamentarium.
utilized in
treatment of urolithiasis including postureteroscopy,
preshockwave lithotripsy,
to relieve symptomatic renal colic,
to provide urinary drainage in nongenitourinary causes of
ureteral obstruction, such as pregnancy and malignant
ureteral obstruction
To serve as a surgical landmark for ureteral identification in
order to avoid iatrogenic ureteral injury in abdominal or
pelvic surgery.

19. Mechanism:
Ureteral stents decrease the frequency and
amplitude of ureteral contractions.
The ureter and ureteral orifice are theorized to
passively dilate from the stent, thus facilitating
drainage.
Available in various sizes, designs & materials.

22. PERCUTANEOUS
NEPHROSTOMY
Primary indication- to relieve an obstructed and
infected renal collecting system.
MERITS:
A wide variety of catheter sizes can be placed (8
French to 18 French) depending on the
characteristics of the fluid being drained.
Can be irrigated when the drainage is purulent or
bloody, to avoid clogging.
UoP of the kidney can be measured.

23. Excessive ureteral manipulation can be avoided,
decreasing the risk for sepsis or rupture.
Can also be done under LA & under conscious
sedation, which eliminates the need for an
anesthesiologist and risks a/w GA.

25. DJ STENT Vs. PCN
Whether urinary drainage is best accomplished via
a ureteral stent or a nephrostomy tube is a subject
of debate.
Both PCN catheters and retrograde internal stents
have been shown to be equally effective in relieving
an obstructed renal collecting system, with similar
complication rates.

26. Percutaneous nephrostomy tube easily placed in
significant hydronephrosis may be even more
successful than retrograde ureteral stenting when
urinary drainage is required as a result of
obstruction of the distal ureter.
One theory of why nephrostomy tubes are
more efficient at relieving obstruction is that
because urine drains around a stent rather than
through the lumen, extraluminal compression from
cancer prevents ureteral peristalsis and precludes
peristent urinary drainage.

27. Percutaneous nephrostomy tubes are
advantageous over ureteral stents in relieving
malignant ureteral obstruction and lowering serum
creatinine.
The percentage of successful retrograde stent
placements is lower than nephrostomy tube
insertion which is nearly always successful in a
dilated system.

28. M/M OF ACUTE PYELONEPHRITIS :
Vast majority of patients respond to conservative
treatment(broad coverage for both gram-negative
and gram-positive organisms).
Few will require ureteral stenting or nephrostomy
tube insertion.
Indications for stenting include:
rising creatinine,
HUN (obstruction with febrile infection), and
intractable pain

29. Even though retrograde stenting by cystoscopy is
attempted initially, if this procedure fails to alleviate
symptoms, PCN insertion is typically pursued.
