Laparoscopic single-incision triangulated umbilical surgery (SITUS) pyeloplasty: a description of the first 32 cases.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
INTRODUCTION AND
objectivesTransumbilical laparoendoscopic (LESS) procedures reduce access trauma. Laparoendocopic single-incision triangulated umbilical surgery (SITUS) utilizes straight instruments in a triangulated fashion, via three trocars placed through a single umbilical incision.
methodsThirty-two consecutive patients underwent an SITUS pyeloplasty. Access is performed by incision of the umbilical fold by 3/4 of its circumference, a 5-mm camera port, and consequently, cranial and caudal 3 or 5 mm working trocars are placed at a distance of 3-6 cm, thus allowing triangulation. SITUS laparoscopy utilizes the standard straight instruments with a length of 43 cm.
resultsAll procedures were successfully performed and no conversion to open, or conventional laparoscopic approach was deemed necessary. Thirty patients underwent a dismembered and two a Fenger pyeloplasty. A crossing vessel was identified in 68.75% of the cases. The median laparoscopic and suturing times were 130 and 30 min, respectively; median blood loss was 50 ml. The median duration of hospitalization was 4 days. The visual analogue scores (VAS) reported were 1 on the first and 0 on the third postoperative day. The indwelling double-J or mono-J stents were removed after a median time of 5 weeks and 4 days, respectively. The overall success rate was 96.8%.
conclusionsThe SITUS technique for pyeloplasty is an attractive alternative to conventional laparoscopy and a viable competitor to LESS surgery. It combines the common principles of traditional laparoscopy, such as conventional instrumentation and triangulation, with the benefits of single-port surgery.
