Malacoplakia is an inflammatory lesion which can affect any organ in the body but predominantly affects the genitourinary system and mainly the bladder. Malacoplakia of the bladder has variable presentations and is associated with urinary infection or immunosuppression. Mullerianosis of the bladder is a rare lesion that consists of two out of the three tissues, endometriosis, endocervicosis, or endosalpingiosis. It is usually associated with a previous cesarean section or pelvic surgery. The diagnosis is confirmed on histopathological examination. Malacoplakia and mullerianosis are usually isolated lesions of the bladder. We present a unique case of coexistence of malacoplakia and mullerianosis in the urinary bladder, reported for the first time in the literature.
Objective:
The objective of this study was to compare mini-percutaneous nephrolithotomy (PCNL) performed by standard and Miniperc techniques in pediatric patients.
Materials and Methods:
This was a retrospective study conducted at our institution between January 2012 and December 2017. The outcomes of pediatric renal stones treated by mini-PCNL done by Miniperc and standard techniques were compared in terms of the drop in the hemoglobin, stone-free rate, and analgesic requirement in the first 24 h.
Results:
A total of 57 children (age: 1–16 years), who underwent mini-PCNL by Miniperc equipment (
n
= 23) and standard equipment (
n
= 34), were included in this study. The postoperative mean drop in hemoglobin was significantly higher in mini-PCNL done by standard compared to the Miniperc technique. The stone-free rate was 95.65% in the Miniperc group and 94.12% in the standard mini-PCNL group. The need for analgesics was significantly lower in the Miniperc group compared to the standard mini-PCNL group (
P
= 0.0002). In the Miniperc group, the majority of the patients required only one dose of analgesics, whereas, in the standard mini-PCNL group, around 44% of the patients required three or more than three doses of analgesics to reduce postoperative pain.
Conclusion:
Both the techniques were safe and efficacious in the management of pediatric renal stone and stone clearance. However, the Miniperc technique resulted in significantly less pain and a lower dosage of analgesics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
