Wallace 2 technique ('head-totail anastomosis'): After spatulation
, the distal ureteric margin is anastomosed to apex of spatulated contralateral ureter.
Impression materials can be mixed manually, via hand spatulation
, or automatically, by using a hand--powered impression gun or an automated mixing machine (Figure 3, left).
This may require a ventral incision and spatulation
of a neomeatus to allow for voiding and decrease the risk of meatal stenosis.
This flap is used for ureteral handling (a "no touch" technique) during pyeloplasty and also serves as a very reliable guide for lateral ureteral spatulation
, preventing ureteral twisting and subsequent misalignment of the de novo ureteropelvic junction.
Composite pastes made up of various resins (Table 4; mass fraction 60%) and ACP fillers (Table 5; mass fraction 40%) were formulated by hand spatulation
provides a good calibre of urethra for better anastomosis.
There are many considerations in this first step such as the type of stone to use, the water to powder ratio, the spatulation
time, the vacuum mixing, and the initial set and final set times.
Despite transaction and spatulation
of dilated proximal ureter in most studies, resection has been rarely applied.
of the right urteter for Wallace type uretero-ureteral anostomosis.
of the ureter, we were able to identify 3 separate benign appearing polyps that were excised using sharp dissection.
