Abstract
Objective: To
investigate and compare the treatment
success of ESWL and URS for the treatment
of ureteral stones.
Materials and method: We
retrospectively identified patients with
solitary kidney who complained of ureteric
stones, treated with ESWL or URS in Aden,
between 2011 and 2014.
The collected parameters
were: age, sex, stone size, and stone
location.
Results:
The total study patients were 90. They
were 64 (71.1%) males and 26 (28.9%) females
with male to female ratio 2.5:1.
Their age ranged
from 17 to 58 years and the mean age was
36.9±11.7 years.
The age group 41
– 50 years represents the highest
percentage of patients 31 (34.5%).
Most patients 68
(75.6%) were aged between 21 – 50
years.
The symptoms were
anuria + nausea + vomiting in 80 (88.9%)
patients and 10 (11.1%) complaining of
dysuria frequency and haematuria. The
mean duration from starting symptoms was
2 ± 0.8 days. The most common side
location was lower ureter 44(48.9%).
The treatment procedure
URS + DJ (double j – ureteric stent)
fixation was predominant with 70 (77.8%)
while the treatment procedure DJ + ESWL
was done for 20 (22.2%) patients. There
was a significant association between
patients’ age groups and sex (p-value
= 0.001).
The frequency of
ureteric stones was significantlyhigher
among males in the age group 41-50 years
26 (28.9%) while in females the frequency
was significantly higher in age group
31-40 years 11 (12.2%). Also, there was
a high statistically significant difference
between the two groups of treatment procedures
related to sex (p = 0.000). In the ESWL
group, females were more than males 13(14.4%).
In the URS group, males were predominant
with 57(63.3%) (p = 0.001).
Success and stone
free rate after ESWL was 85%, while in
the URS group it was successful in all
patients - stone-free 100% (p < 0.05).
Conclusion:
URS seems to be more successful in the
treatment of ureteral stones; further
prospective studies with more patients
are needed to clarify our results.
